Joseph McKenzie Williams appeals his conviction and sentence for possession of heroin with intent to distribute, in violation of 21 U.S.C. § 841 (2000). He contends that the district court erred in denying his motion to suppress evidence because his stop, arrest, and detention were not supported by probable cause. We review a district court’s legal determinations de novo. Ornelas v. United States, 517 U.S. 690, 699, 116 S.Ct. 1657, 134 L.Ed.2d 911 (1996); United States v. Rusher, 966 F.2d 868, 873 (4th Cir. 1992). When a suppression motion has been denied, we review the evidence in the light most favorable to the government. See United States v. Seidman, 156 F.3d 542, 547 (4th Cir. 1998).

Williams argues that the informant used by the police was not rehable and therefore did not provide probable cause. We hold that the information provided by the informant contained sufficient indicia of reliability because lying would have been against his penal interests. See United States v. Miller, 925 F.2d 695, 699 (4th Cir. 1991). We have reviewed the record and conclude that under the totality of the circumstances, sufficient probable cause existed to support Williams’s stop, arrest, and detention. See Illinois v. Gates, 462 U.S. 213, 230-32, 103 S.Ct. 2317, 76 L.Ed.2d 527 (1983); United States v. Singh, 363 F.3d 347, 354, 2004 WL 691524, at *5 (4th Cir. Apr.2, 2004).

Accordingly, we affirm Williams’s conviction and sentence. 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.
