Glen Harvick appeals his conviction for importation of methylenedioxymethamphetamine (MDMA) and aiding and abetting, contending that the district court should have granted his motion to suppress. Relying on Wilson v. Arkansas, 514 U.S. 927, 931, 115 S.Ct. 1914, 131 L.Ed.2d 976 (1995), and 18 U.S.C. § 3109, Harvick argued in the district court that the officers did not comply with the “knock and announce” rule before entering the apartment where the MDMA was found.

On appeal, Harvick challenges only the district court’s factual determination that the officers did not conduct an unannounced entry in violation of the Fourth Amendment. After reviewing the transcript of the suppression hearing, we conclude that the district court did not commit clear error in finding that the entry did not violate the “knock and announce” principle. See United States v. Santiago, 310 F.3d 336, 340 (5th Cir. 2002).

AFFIRMED.
