The Federal Public Defender appointed to represent Rosendo Arias-Samano 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), and United States v. Flores, 632 F.3d 229 (5th Cir.2011). Arias-Samano has filed a response. The record is not sufficiently developed to allow us to make a fair evaluation of Arias-Sama-no’s claim of ineffective assistance of counsel; we therefore decline to consider the claim without prejudice to collateral review. See United States v. Isgar, 739 F.3d 829, 841 (5th Cir.), cert. denied, — U.S. -, 135 S.Ct. 123, 190 L.Ed.2d 94 (2014).
We have reviewed counsel’s brief and the relevant portions of the record reflected therein, as well as Arias-Samano’s response. We concur with counsel’s assessment that the appeal presents no non-frivolous issue for appellate review. Accordingly, Arias-Samano’s motion for the appointment of new counsel is DENIED, *374the motion for leave to withdraw is GRANTED, counsel is excused from further responsibilities herein, and the APPEAL IS DISMISSED. See 5th Cm. R. 42.2. Arias-Samano’s motion for an extension of time is DENIED as moot.
