OPINION
CONTIE, Circuit Judge.


1
Defendant-appellant, Tony Peters, appeals his conviction for possession with intent to  distribute heroin. For the following reasons, we affirm.

I.

2
On February 21, 1997, three agents of the Drug Enforcement Administration ("DEA") in Toledo, Ohio were assigned to  work drug interdiction at the Amtrak Railroad Station. At approximately 8 a.m., the team observed passengers  disembarking from a train that had traveled to Toledo from New York. At about 9 a.m., members of the team observed the  defendant herein leaving the train, carrying a distinctive black attache case tucked underneath his arm. Although it was a  cloudy day, defendant was wearing sunglasses.


3
The surveillance continued and the team observed defendant enter the train station, go directly to a pay phone, and  make a telephone call. While making the call, defendant looked around the train station as if he were conducting  countersurveillance. After defendant finished making the call, he went out of the train terminal and boarded a bus whose  destination was Detroit, Michigan. Before seating himself, defendant was observed placing the black attache case in an  overhead rack on the opposite side of the bus.


4
One of the officers (all of whom were dressed in civilian attire) approached defendant, identified himself, and inquired  whether he could speak with him. Defendant agreed, and Officer Stout requested to see his ticket. The ticket was issued in  the name of Tony Morris. After observing the ticket, Officer Stout immediately returned it to defendant Peters. Officer  Stout asked whether defendant Peters had any other identification, and he produced a New York Learner's Permit bearing  the name Shennaike Adedayo. When Officer Stout asked defendant why he was traveling under an assumed name, he  became nervous, bowed his head, and mumbled.


5
Officer Stout asked defendant about his destination and purpose for travel. Defendant replied that he was traveling to Detroitto see his aunt and that he was going to stay about two weeks. However, when Officer Stout asked defendant Peters  if he had any luggage, the response was no. Special Agent Ellinwood, another member of the team, witnessed this  conversation. Ellinwood then removed the black attache case from the overhead rack and asked defendant Peters if he had  carried the bag from the train station onto the bus. Defendant denied owning the bag, carrying it through the station to the  bus, or placing it into the overhead rack.


6
Defendant was then asked to get off the bus momentarily for further inquiry. Special Agent Ellinwood placed the bag  among the other luggage beneath the bus, and another agent, Deputy Corbett, subjected the luggage to a canine sniff. The  drug-detecting canine positively alerted to the bag, and defendant Peters was placed under arrest. Shortly thereafter, a  search warrant to open the bag was obtained, and the bag's contents were examined.


7
The agents found approximately 400 grams of pure heroin inside the bag. They also found a page from a calendar with  the name of Tony Morris, the name that was on defendant's ticket, and the arrival and departure times for the train, as well  as a confirmation number which matched the ticket that defendant Peters possessed.


8
On March 5, 1997, a federal grand jury sitting in the Northern District of Ohio returned an indictment charging  defendant, Tony Peters, aka Shennaike Adedayo, with possession with intent to distribute approximately 400 grams of  heroin in violation of 21 U.S.C. §841(a)(1). After hearing evidence on the motion to suppress and other matters not  subject to this appeal, the case was set for a jury trial, which began on October 28, 1997. On April 21, 1997, defendant  Peters filed a motion to suppress the evidence. On June 2, 1997 and June 12, 1997, a hearing was held before a magistrate  judge, who issued a report and recommendation denying the motion, which the district court adopted.


9
At trial, defendant testified in his own defense. He stated that he was traveling from New York to Detroit in order to  purchase an automobile. He alleged that he was traveling "light," with no luggage because he planned to return the same  day. He denied that he had ever carried a black attache case and maintained that the three officers who had observed him  were either mistaken or lying. He stated that he used alias names because his real name was difficult to pronounce. He  maintained that the calendar note containing the travel information, which was found inside the black attache case and  which was government's Exhibit 4 at trial, had been found on his person when the officer searched him after his arrest.


10
On October 29, 1997, a jury returned a guilty verdict. On February 27, 1998, the district court sentenced defendant to a  term of imprisonment of 120 months. Defendant timely filed this appeal.

II.

11
We must first decide whether the district court properly denied defendant's motion to suppress the evidence found in the  black attache case.


12
Defendant contends that the police did not have reasonable suspicion to question him and that the seizure and search of  the black attache case was unconstitutional. On appeal, the United States argues that defendant does not have standing to  challenge the search of the black attache case because he denied ever maintaining any custody, control, ownership,  possession, or interest in the black attache case which was subjected to the search, and therefore he has no standing to  object to the search.


13
We agree with the United States that defendant lacks standing. A person has standing to challenge the admissibility of  contraband found in a suitcase or travel bag only if one has a legitimate expectation of privacy in the bag at the time of the  search.  See Katz v. United States, 389 U.S. 347,353 (1967). A legitimate expectation of privacy incorporates two  elements: first, whether defendant "exhibited an actual (subjective) expectation of privacy," and second, whether the  defendant's subjective expectation is "one that society is prepared to recognize as reasonable." United States v. Tolbert,  692 F.2d 1041, 1044 (6th Cir. 1982), cert. denied, 464 U.S. 933 (1983). "[D]efendants charged with crimes of possession  may only claim the benefits of the exclusionary rule if their own Fourth Amendment rights have in fact been violated." United States v. Salvucci, 448 U.S. 83, 85 (1980). This and other circuits have recognized that "[o]ne who disclaims any  interest in luggage thereby disclaims any concern about whether or not the contents of the luggage remain private." United  States v. Tolbert, 692 F.2d at 1045 (quoting United States v. Miller, 589 F.2d 1117, 1131 (1st Cir. 1978)). Cf. United  States v. Sanders, 719 F.2d 882, 886 (6th Cir. 1983) (affirmative disclaimer required for privacy right to be lost). Thus, in  the present case, this court must determine whether defendant exhibited a subjective expectation of privacy in the attache  case, and whether the expectation is one that society is prepared to protect. See Smith v. Maryland, 442 U.S. 735, 743  (1979).


14
In United States v. Tolbert, this court addressed these issues in a situation similar to the one in the present case. In Tolbert, the defendant was approached by law enforcement officers at an airport. The officers identified themselves and  asked to examine the defendant's ticket and identification, which the defendant allowed. 692 F.2d at 1043. The defendant  later disclaimed ownership of the luggage, which the officers then searched and discovered cocaine. This court held in Tolbert that "because, by her actions and vigorous oral disclaimers, [the defendant] affirmatively indicated that she had no  interest in preserving the secrecy of the contents of the suitcase, she had no legitimate expectation of privacy therein." Id. at 1045. The court in Tolbert found that the defendant had no Fourth Amendment right to object to the search of the  suitcase in which she had no legitimate expectation of privacy. Id. at 1044-45.


15
The factual scenario involved in the present case is also similar to the one involved in United States v. Frazier, 936  F.2d 262 (6th Cir. 1991). In Frazier, the defendant's companion had placed a bag on the floor of the Los Angeles airport  when they were approached by special agents. They left the bag on the floor when they went to a seating area nearby to  converse with the officers. In Frazier, when one detective asked about the bag, the defendant stated that it was not his.  This court held that the "disclaimer constituted an abandonment that resulted in [the defendant's] lack of standing to  challenge the search." Id. at 265 (quoting United States v. Knox, 839 F.2d 285, 294 (6th Cir. 1988)). See also United States  v. Collis, 766 F.2d 219, 222 (6th Cir.) ("[T]he defendant abandoned the shoulder bag and failed to establish a legitimate  subjective expectation of privacy which would confer standing to raise a fourth amendment challenge to the agents' search  of the bag"), cert. denied, 474 U.S. 851 (1985). The court in Frazier determined that by abandoning the black bag, the  defendant also abandoned any legitimate privacy expectation in regard to it. 936 F.2d at 265. A similar rationale applies in  the present case. Defendant vigorously denied that the black attache case was owned by him or put on the bus by him, and  thus he has no interest in preserving the secrecy of the contents of the bag and has no legitimate expectation of privacy,  which would confer standing. We conclude that by voluntarily abandoning the black attache case, defendant forfeited any  reasonable expectation of privacy, and, therefore, he does not have standing to challenge the search of it.


16
Defendant claims, however, that his abandonment of the bag resulted from an improper seizure, and the contents are  therefore inadmissible fruit of the poisonous tree. See Tolbert, 692 F.2d at 1045 ("an unconstitutional seizure or arrest  which prompts a disclaimer of property vitiates that act"). It is true that defendant's disclaimer of ownership of the bag  precludes exclusion of the evidence found in it unless the abandonment was prompted by an unconstitutional seizure or  arrest. United States v. Morin, 665 F.2d 765, 770 (5th Cir. 1982).


17
The appropriate test for determining a "seizure" when one is approached by police at a public place, such as a bus  terminal, was enunciated in United States v. Mendenhall, 446 U.S. 544 (1980):


18
We conclude that a person has been "seized" within the meaning of the Fourth Amendment only if, in view of all of  the circumstances surrounding the incident, a reasonable person would have believed that he was not free to leave.  Examples of circumstances that might indicate a seizure, even where the person did not attempt to leave, would be  the threatening presence of several officers, the display of a weapon by an officer, some physical touching of the  person of the citizen, or the use of language or tone of voice indicating that compliance with the officer's request  might be compelled.


19
Id. at 554 (citations and footnote omitted). Thus, under the Mendenhall test, a "person is 'seized' only when, by means of  physical force or a show of authority, his freedom of movement is restrained." Id. at 553.


20
In Frazier, this court found the defendant's abandonment of the bag was not the result of an unconstitutional seizure.  936 F.2d at 265. The factual scenario leading up to the seizure in Frazier was similar to that of the present case. In Frazier,  two agents approached a group and asked defendant and his companions if they could ask them some questions. After the  defendant denied that he was traveling, he was observed to have a boarding pass in his possession. The agent asked the  defendant if he could see his ticket, which the defendant had in his pocket. The defendant handed over the ticket, and the  agent then asked the defendant whether the black bag, which had been seen in his possession, belonged to him. The  defendant responded that the bag was not his and that he had never seen it. Id. at 263. This court held in Frazier that  because the defendant voluntarily gave the ticket to the officer and the officer did not refuse to return the ticket to the  defendant, taking the ticket did not constitute a seizure. Id. at 265. Similarly, in the present case, defendant voluntarily  gave his ticket to Officer Stout, who immediately returned it to him. See also United States v. Winfrey, 915 F.2d 212, 216  (6th Cir. 1990) ("[t]he request for, and examination of, an airline ticket and driver's license do not amount to a seizure  under the fourth amendment"), cert. denied, 498 U.S. 1039 (1991).


21
Defendant asserts that the special agents' initial encounter and subsequent conversations with him were not consensual,  alleging that the police conduct surrounding the encounter caused him to believe "that he was not free to ignore the police  presence or that he was free to go," because he had seen other black people searched by the same men. However, defendant  did not attempt to support his motion to suppress with this evidence of coercive police activity before either the magistrate  judge during the hearing on the motion to suppress or before the district court when it ruled on his motion to suppress. It is  well-settled law that we will not consider an argument that has not been made before the district court. Pinney Dock &  Transport Co. v. Penn Cent. Corp., 838 F.2d 1445, 1461 (6th Cir.), cert. denied, 488 U.S. 880 (1988).


22
At the hearing on the motion to suppress, Special Agent Ellinwood testified that Special Agent Stout approached  defendant and identified himself. At the time, both agents were dressed in civilian clothing and neither had any weapons or  other police paraphernalia showing. During the encounter with defendant, Stout simply asked to see his bus ticket, train  ticket, or other identification, whether he had any luggage, and his purpose for travel. The transcript of the suppression  hearing indicates that the officers did not engage in any overbearing or coercive activity in making these requests and that a  consensual encounter occurred. We find that there is nothing to indicate that the officers conveyed a message that  compliance with their request to speak with defendant and examine his ticket was required, and no Terry stop occurred. As  the Supreme Court stated in Florida v. Bostick, 501 U.S. 429 (1991), no seizure occurs when police "ask questions of [an]  individual, ask to examine the individual's identification, and request consent to search his or her luggage--as long as the  officers do not convey a message that compliance with their requests is required." Id. at 435 (citations omitted). See alsoUnited States v. Frazier, 936 F.2d at 265; United States v. Winfrey, 915 F.2d at 216. Because law enforcement officials  may approach individuals and propose initial questions without having any reasonable suspicion of criminal activity, if the  police do nothing to convey to the defendant that he is not free to leave, the encounter does not become a seizure for  Fourth Amendment purposes as long as the individual consents to questioning, which the defendant herein did. Absent  coercive or intimidating behavior which negates the reasonable belief that compliance is not compelled, the agent's request  for additional identification and voluntarily given information from the defendant does not constitute a seizure under the  Fourth Amendment. See Florida v. Rodriguez, 469 U.S. 1, 5 (1984); Florida v. Royer, 460 U.S. 491, 497 (1983).


23
Although defendant states that he did not feel free to go, at the motion to suppress hearing he provided no objective  evidence to support this subjective belief. Because the transcript of the hearing indicates there was no coercive activity on  the part of the special agents up to the point when they asked if the suitcase belonged to him, the stop remained a  consensual encounter, which does not require reasonable suspicion for Fourth Amendment purposes. It was during this  consensual encounter when defendant abandoned ownership of the bag, and thus the search of the bag after a search  warrant was obtained was not the result of an unconstitutional seizure. Because defendant abandoned ownership of the bag  during a consensual encounter, he waived any right to a legitimate expectation of privacy therein, and defendant therefore  has no standing to challenge the subsequent search of the bag. The district court's denial of the motion to suppress  evidence is affirmed.

III.

24
We must next review whether there was sufficient evidence to sustain defendant's conviction. When this court reviews  a claim that the evidence was insufficient to support a conviction, this court views the evidence and all reasonable  inferences in the light most favorable to the government. United States v. Morrow, 977 F.2d 222, 230 (6th Cir. 1992), cert.  denied, 508 U.S. 975 (1993). According to the Supreme Court opinion in Jackson v. Virginia, 443 U.S. 307, 319 (1979), a  conviction will be upheld if "any rational trier of fact could have found the essential elements of the crime beyond a  reasonable doubt." Upon appeal, the court should not weigh the evidence or determine the credibility of the witnesses. United States v. Warner, 971 F.2d 1189, 1195 (6th Cir. 1992).


25
Defendant argues that in the present case the jury overlooked a number of important factors in weighing the evidence,  such as the absence of his fingerprints on the bag that contained the heroin, the fact that he had little cash on his person,  and the statements that he voluntarily made prior to being arrested. Defendant's arguments have no merit for the following  reasons.


26
On appeal, the reviewing court is not to weigh the evidence or determine the credibility of witnesses. Id. Furthermore,  we must construe the evidence in the light most favorable to the government. Morrow, 977 F.2d at 230. In so doing, none  of the things which defendant mentions are sufficient to mean that no rational trier of fact could have found the essential  elements of the crime beyond a reasonable doubt. For example, the testimony regarding fingerprints established that  although an attempt had been made to recover fingerprints from the bag, subsequent examination could not prove  conclusively, one way or another, whether the fingerprints on it were defendant's. However, this does not prove that he  never handled the bag, which three DEA agents observed him carrying.


27
Defendant's argument that because he had little cash on his person, he was not a heroin dealer also fails. It is the  government's position that defendant was transporting the drugs from New York to Detroit, the final place of distribution.  It is therefore logical that defendant would have been paid for the heroin once it had been ultimately delivered to the  purchaser in Detroit, and there was no reason for him to have a large amount of cash on his person on his way to Detroit  prior to final delivery.


28
Finally, in regard to defendant's statement to the jury in his defense, the jury obviously did not find him credible, and  this court must not weigh the credibility of the witnesses. Warner, 971 F.2d at 1195. Moreover, this determination of the  jury is supported by the evidence, because defendant's statements made at trial were often in direct conflict with what he  said prior to his arrest. For example, he told the police that he had planned to remain in Detroit for about two weeks when  he was first arrested, whereas at trial he insisted that he intended to return to New York the same day. He told the police  that he had not carried the bag from the train through the station to the bus, although he had clearly been seen to do so by  three DEA agents. Prior to his arrest, defendant told Officer Stout that his clothes were at his aunt's house, whereas at trial  he stated that he had no clothes. The jury had the opportunity to view the three agents' testimony, observe their demeanor,  and assess the reasonableness of their testimony, and compare this with the conflicting statements of defendant.


29
In considering the record as a whole and taking all the inferences in the light most favorable to the government, there  was more than sufficient evidence to permit a rational trier of fact to find that defendant committed the offense beyond a  reasonable doubt. Three DEA agents saw him place the suitcase in the rack opposite himself; they found a calendar page  inside the bag with the name of Tony Morris, which was the name on defendant's ticket. The calendar page also had the  arrival and departure times for the train which the agents were surveilling, as well as the confirmation number which  matched the ticket that defendant Peters possessed. Therefore, there was a direct connection between the bag and  defendant, and the jury found his argument that the agents planted the calendar page in the bag not credible. We must give  this credibility determination of the jury its due weight. For these reasons, the district court is affirmed on this issue.

IV.

30
For the above reasons, the district court is hereby AFFIRMED.
