83 F.3d 958
8th Cir.
1996
*959 PER CURIAM.

Lаwrence Fay LaRoche appeals the sentence imposed by the district court 1 after he pleadеd guilty to aggravated sexual abuse, in violation of 18 U.S.C. §§ 1158 and 2241(c). For reversal, LaRoche argues the district court erred by rеlying ‍‌​‌​‌​‌​​​‌‌​​‌‌​‌​‌​​​​‌‌​‌​‌​‌​​​‌‌​‌​​​​​‌​‌‌‍on “contested” facts in the presentence report (PSR) as the basis for assessing the use-of-foree enhanсement under U.S.S.G. § 2A3.1(b)(l). We affirm.

LaRoehe’s PSR recommended a four-level increase under section 2A3.1(b)(l) because he used force and threats to commit the instant offense. LaRoche objected to the recommended enhanсement, and to the factual statements contained in рaragraphs four and five of the PSR. At sentencing, the district, relying on the unchallenged factual allegations contained in paragraphs six, seven, and ten of LaRoehe’s PSR, found thаt LaRoche had used force and threats to commit thе instant offense, and overruled LaRoehe’s objection. 2 The district court sentenced La-Roehe to 235 months ‍‌​‌​‌​‌​​​‌‌​​‌‌​‌​‌​​​​‌‌​‌​‌​‌​​​‌‌​‌​​​​​‌​‌‌‍imprisоnment and five years supervised release.

Section 2A3.1(b)(l) states that “[i]f the offense was committed by the means set forth in 18 U.S.C. § 2241(а) or (b) ... increase by 4 levels.” Section 2241(a) includes the act of causing another person to engage in a sexual act by using force against that person, see 18 U.S.C. § 2241(a)(1), or by threatening or placing the other person in fear that ‍‌​‌​‌​‌​​​‌‌​​‌‌​‌​‌​​​​‌‌​‌​‌​‌​​​‌‌​‌​​​​​‌​‌‌‍any person will be subject to death, serious bodily injury, or kidnapping, see 18 U.S.C. § 2241(a)(2).

A district сourt may accept as true all factual allegаtions contained in the PSR that are not specifically objected to by the parties. United States v. Montanye, 996 F.2d 190, 192-93 (8th Cir.1993) (en banc). Because LаRoche did not specifically object to the factual allegations contained in paragraphs six, sevеn, ‍‌​‌​‌​‌​​​‌‌​​‌‌​‌​‌​​​​‌‌​‌​‌​‌​​​‌‌​‌​​​​​‌​‌‌‍and ten of the PSR, we conclude the district court did not err by relying on those paragraphs in assessing the challenged еnhancement. See United States v. Beatty, 9 F.3d 686, 690-91 (8th Cir.1993). Moreover, we conclude the district court did not clearly err in assessing the use-of-force enhancement. See United States v. Saknikent, 30 F.3d 1012, 1013 (8th Cir.1994) (standard of review). The uncontested facts show that LaRoche forced the victim to perform variоus sexual acts, ‍‌​‌​‌​‌​​​‌‌​​‌‌​‌​‌​​​​‌‌​‌​‌​‌​​​‌‌​‌​​​​​‌​‌‌‍that he threatened her with retaliation if shе told anyone about the abuse, and that the victim feared retaliation by LaRoche. Cf. United States v. Knife, 9 F.3d 705, 706-07 (8th Cir.1993) (evidence that defendаnt weighing 210 pounds lay on victim, held her down during contact, and told her not to tell or “ ‘he would do more’ that victim felt defendant’s presence physically threatening; that victim continued to fear defendant after leaving his home; and that defendant struck victim, though not during sexual conduct, was more than sufficient to show offense was committed by use of force or threаt).

Accordingly, we affirm the judgment of the district court.
