On November 18, 2004, this court affirmed Wayne Allen Fletcher’s convictions and sentence. See United States v. Fletcher, 113 Fed.Appx. 545 (4th Cir. 2004) (unpublished). On May 16, 2005, the Supreme Court of the United States granted Fletcher’s petition for writ of certiorari, vacated our judgment and remanded the case to this court for further consideration in light of United States v. Booker, 543 U.S. 220, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005). We vacate the sentence and remand for resentencing.

In Booker, the Supreme Court held Blakely v. Washington, 542 U.S. 296, 124 S.Ct. 2531, 159 L.Ed.2d 403 (2004), applied to the federal sentencing guidelines and that the mandatory manner in which the guidelines required courts to impose sen- *270 fencing enhancements based on facts found by the court by a preponderance of the evidence violated the Sixth Amendment. Thus, when a defendant pleads guilty and is sentenced under the mandatory guidelines scheme, “[a]ny fact (other than a prior conviction) which is necessary to support a sentence exceeding the maximum authorized by the facts established by a plea of guilty or a jury verdict must be admitted by the defendant or proved to a jury beyond a reasonable doubt.” Booker, 125 S.Ct. at 756.

In United States v. Hughes, 401 F.3d 540 (4th Cir. 2005), we held that a sentence imposed under the pre-Booker mandatory sentencing scheme that was enhanced based on facts found by the court, not by a jury (or, in a guilty plea ease, admitted by the defendant), constitutes plain error. That error affects the defendant’s substantial rights and warrants reversal under Booker when the record does not disclose what discretionary sentence the district court would have imposed under an advisory guideline scheme. Hughes, 401 F.3d at 546-56.

Because the district court engaged in judicial fact-finding to determine Fletcher’s offense level and the resulting guideline range was imposed in a mandatory manner, there was a Sixth Amendment violation under Booker. 1 On remand, the court must calculate the appropriate guideline range, consider the range in conjunction with other relevant factors under the guidelines and 18 U.S.C.A. § 3553(a) (West 2000 & Supp. 2005), and impose a sentence. If a court imposes a sentence outside the guideline range, the district court must state its reasons for doing so. Hughes, 401 F.3d at 546.

Accordingly, we vacate the sentence and remand for further consideration in light of Booker and Hughes. 2 , 3 We dispense with oral argument because the facts and legal contentions are adequately presented in the materials before the court and argument would not aid the decisional process.
