NOTICE:  Eighth Circuit Rule 28A(k) governs citation of unpublished opinions and provides that they are not precedent and generally should not be cited unless relevant to establishing the doctrines of res judicata, collateral estoppel, the law of the case, or if the opinion has persuasive value on a material issue and no published opinion would serve as well.UNITED STATES OF AMERICA, Appellee,v.Lionel Scott JOHNSON, Appellant.
No. 96-3106.
United States Court of Appeals, Eighth Circuit.
April 1, 1997.

Before McMILLIAN, MAGILL, and MORRIS SHEPPARD ARNOLD, Circuit Judges.
PER CURIAM.


1
Lionel Scott Johnson pleaded guilty to knowingly transporting a person in interstate commerce for the purpose of engaging in sexual activity, in violation of 18 U.S.C. § 2421.  The district court1 sentenced him to 60 months imprisonment--to be consecutive to an undischarged state sentence Johnson was currently serving in Iowa--and three years supervised release.  On appeal, Johnson's appointed counsel moved to withdraw and filed a brief pursuant to Anders v. California, 386 U.S. 738 (1967), with the stated issue that the court erred in refusing to credit Johnson for time served in state prison since the filing of the federal indictment.  In a pro se supplemental brief, Johnson seeks to withdraw his guilty plea, stating that his plea was not knowing and voluntary.


2
Having reviewed the record in accordance with Penson v. Ohio, 488 U.S. 75, 80 (1988), and finding no nonfrivolous issues for appeal, we grant counsel leave to withdraw and deny Johnson's motion for appointment of new counsel.  We conclude the district court did not err in refusing to credit Johnson for time served.  See United States v. Iversen, 90 F.3d 1340, 1344-45 (8th Cir.1996) (district court does not have authority to credit defendant for time served;  such claim should be presented in first instance to Bureau of Prisons).  We do not consider Johnson's claim that his guilty plea was not knowing and voluntary, as such a claim must first be presented to the district court.  See United States v. Murphy, 899 F.2d 714, 716 (8th Cir.1990).


3
Accordingly, the judgment of the district court is affirmed.
