Randy Baker, federal prisoner # 75188-079, was convicted of conspiracy to possess with intent to distribute a controlled substance and is serving a 30-year sentence in federal custody. Baker filed an application, under 28 U.S.C. § 2241, contending that he should have received credit against his federal sentence for time served in state custody between the date of his arrest and the date on which he was turned over to federal authorities to begin serving his federal sentence. The district court determined that Baker was not entitled to credit for time served in state custody related to a state parole violation. Baker contends that he should have received credit for that period because his parole was revoked as a result of the joint federal and state investigation leading to his federal conviction. This argument is without merit.

Baker did not receive credit against his federal sentence from the date his state parole violation sentence commenced, on October 21, 1997, through the date on which he was transferred to federal custody pursuant to a federal detainer, on June 4, 2001, because that time was credited against a prior undischarged sentence. The summary judgment evidence shows that Baker would have been required to serve the state parole violation sentence if the federal detainer had not been in place. See Ballard v. Blackwell, 449 F.2d 868, 869 (5th Cir. 1971). The judgment is

AFFIRMED.
