OPINION

PER CURIAM:

Demont Blue appeals his conviction and sentence for possession of
cocaine base with the intent to distribute in violation of 21 U.S.C.
§ 841(a)(1) (1994). Finding no error, we affirm.

Blue first contends that the district court denied him a fair trial by
interrogating him before the jury. Federal Rule of Evidence 614(b)
authorizes a trial judge to interrogate witnesses. This interrogation is
reviewed for an abuse of discretion with the seminal question being
whether the district court imposed its own view of the evidence on the
jury. See United States v. Wilson, 118 F.3d 228, 237 (4th Cir. 1998).
We conclude that the district court did not in any way impose its view
of the evidence on the jury. Rather, the questions appear to have been
aimed at developing the facts of the case. As such, the examination
was not an abuse of discretion.* See United States v. King, 119 F.3d
290, 294 (4th Cir. 1997) (holding that while district court must main-
tain impartiality, it may still interrogate witnesses as necessary to
ensure proper development of the facts).

Blue next argues that the district court erred in denying his motion
to suppress. This Court reviews a district court's factual findings in
a motion to suppress for clear error and its legal conclusions de novo.
See United States v. Rusher, 966 F.2d 868, 873 (4th Cir. 1992). In
support of his assertion, Blue argues that he was"seized" when a
police officer followed him after he began to walk away from a vol-
untary police encounter. Blue's very action of walking away from the
officer, however, indicates that he believed he was free to leave.
Thus, there was no seizure.
_________________________________________________________________
*We also note that the court gave an appropriate instruction to the jury
that the court's comments were not to be construed as expressing any
opinion on the case and were to be disregarded.

                    2
For a seizure to have occurred, there must have been either an
application of physical force, or a show of authority to which Blue
yielded. See California v. Hodari D., 499 U.S. 621 (1991). This did
not occur until after Blue ran from the first officer and collided with
a second, resulting in Blue's fall to the ground. We find that the facts
known to the officers at this time, taken in their totality, create a rea-
sonable suspicion that criminal activity was afoot so as to justify the
second officer's "seizure" of Blue by impeding his flight. See United
States v. Cortez, 449 U.S. 411, 417 (1981) (explaining "totality of cir-
cumstances" standard). We thus find no error in the district court's
denial of Blue's suppression motion.

Finally, Blue contends that the district court erred in employing the
Sentencing Guidelines' provisions dealing with crack cocaine because
there was insufficient evidence that the drug involved was crack, as
opposed to another form of cocaine base. In reviewing the district
court's application of the Guidelines, this Court reviews legal deter-
minations de novo and factual determinations for clear error. See
United States v. Blake, 81 F.3d 498, 503 (4th Cir. 1996). We conclude
there was sufficient evidence that the cocaine base which Blue was
carrying was crack cocaine. Thus, we find no clear error in the district
court's finding that the drug was crack cocaine and in its subsequent
application of the 100:1 sentencing ratio.

For these reasons, we affirm Blue's conviction and sentence. We
dispense with oral argument because the facts and legal contentions
are adequately presented in the materials before the court and argu-
ment would not aid the decisional process.

AFFIRMED
