The attorney appointed to represent Charles Gillespie has moved for leave to withdraw and has filed a brief in accordance with Anders v. California, 386 U.S. 738, 87 S.Ct. 1396, 18 L.Ed.2d 493 (1967). Gillespie has not filed a response to the Anders motion but did bring claims of ineffective assistance of counsel to this court’s attention. The record is insufficiently developed to allow consideration at this time of Gillespie’s claims of ineffective assistance of counsel; such claims generally “cannot be resolved on direct appeal when [they have] not been raised before *650 the district court since no opportunity existed to develop the record on the merits of the allegations.” United States v. Cantwell, 470 F.3d 1087, 1091 (5th Cir. 2006) (internal quotation marks and citation omitted). Our independent review of the record and counsel’s brief discloses no non-frivolous issue for appeal. Accordingly, counsel’s motion for leave to withdraw is GRANTED, counsel is excused from further responsibilities herein, and the APPEAL IS DISMISSED. See 5th Cir. R. 42.2.
