[UNPUBLISHED]

David Sweet appeals from the district court’s 1 dismissal of his 28 U.S.C. § 2241 petition, in which he sought credit on his federal sentence for time he spent in state custody. We agree with the district court that Sweet was not entitled to federal *602 credit, because the record shows that the period of state detention at issue was credited against his state sentence. See 18 U.S.C. § 3585(b) (“A defendant shall be given credit toward the service of a term of imprisonment for any time he has spent in official detention prior to the date the sentence commences ... that has not been credited against another sentence.”); United States v. Kramer, 12 F.3d 130, 132 (8th Cir. 1993) (this statute prohibits double credit, i.e., federal prisoner is not entitled to credit on federal sentence when he received credit toward his state sentence for same time period), cert. denied, 511 U.S. 1059, 114 S.Ct. 1629, 128 L.Ed.2d 352 (1994).

Accordingly, we affirm. See 8th Cir. R. 47B.
