Mohamed Admed Hassan Abdallah Om-ran, 1 immigration detainee # A079680001, appeals the district court’s dismissal of his Bivens 2 and Federal Tort Claims Act (FTCA) complaint as frivolous, for failure to state a claim upon which relief could be granted, and for lack of jurisdiction. See 28 U.S.C. §§ 1915(e)(2)(B), 1915A, 2680(c). Omran alleged that U.S. Marshal Nicole *132 Roy and a computer expert deleted or erased personal computer files from Om-ran’s computer while it was in the custody of the United States Marshals.

We review the district court’s §§ 1915(e)(2)(B) and 1915A dismissal of Omran’s Bivens claim de novo. See Samford v. Dretke, 562 F.3d 674, 678 (5th Cir. 2009); Geiger v. Jowers, 404 F.3d 371, 373 (5th Cir. 2005). To the extent that Omran asserted that Roy and the expert negligently deleted his electronic data, such a claim does not implicate the Due Process Clause. See Daniels v. Williams, 474 U.S. 327, 328, 106 S.Ct. 662, 88 L.Ed.2d 662 (1986); Lewis v. Woods, 848 F.2d 649, 652 (5th Cir. 1988). Such a claim thus lacks an arguable basis in law and is frivolous. See Brewster v. Dretke, 587 F.3d 764, 767 (5th Cir. 2009).

Although the intentional deprivation of property by a government official may amount to a due process violation in certain cases if the deprivation is authorized and not random, see Stotter v. Univ. of Tex. at San Antonio, 508 F.3d 812, 822 (5th Cir. 2007), Omran has not alleged facts showing either an authorized or deliberate deletion of his computer data and thus he has failed to state a claim of an intentional deprivation of property under Bivens. See In re Katrina Canal Breaches Litigation, 495 F.3d 191, 205 (5th Cir. 2007).

We review de novo the district court’s dismissal for lack of jurisdiction of Om-ran’s FTCA claim. See Leleux v. United States, 178 F.3d 750, 754 (5th Cir. 1999). The FTCA waives the sovereign immunity of the United States for “claims arising out of torts committed by federal employees.” Ali v. Fed. Bureau of Prisons, 552 U.S. 214, 217-18, 128 S.Ct. 831, 169 L.Ed.2d 680 (2008). However, “[t]he FTCA exempts from this waiver certain categories of claims,” id. at 218,128 S.Ct. 831, including, as relevant here, claims arising from the detention of property by customs officers, excise officers, and “any other law enforcement officer,” § 2680(c). See Ali, 552 U.S. at 218, 128 S.Ct. 831. Because employees of the U.S. Marshals Service are such other law enforcement officers, see Schlaebitz v. United States Dept. of Justice, 924 F.2d 193, 195 (11th Cir. 1991), the district court properly concluded that it was without jurisdiction to consider Omran’s FTCA claim. See Ali, 552 U.S. at 218, 228, 128 S.Ct. 831; Leleux, 178 F.3d at 754.

We do not consider Omran’s stated reference to a claim under the Fourth Amendment as he has briefed no argument on the issue. See Morrison v. City of Baton Rouge, 761 F.2d 242, 244 (5th Cir. 1985). Nor do we address Omran’s contention that the defendants conspired to deprive him of his constitutional rights based on his racial ethnicity and national origin. Omran raised this issue for the first time in his objection to the magistrate judge’s report and recommendation and alleged no facts in support of the claim in the district court or in this court. See Cupit v. Whitley, 28 F.3d 532, 535 n.5 (5th Cir. 1994). To the extent he was attempting in the district court to amend his complaint to add this conelusory assertion, the district court acted within its discretion in declining to allow such amendment. See United States v. Riaseos, 76 F.3d 93, 94 (5th Cir. 1996).

Because Omran’s appeal is without arguable merit, it is dismissed as frivolous. See Howard v. King, 707 F.2d 215, 219-20 (5th Cir. 1983); 5th Cir. R. 42.2. Omran’s motion for the appointment of counsel on appeal is denied.

The dismissal of the instant appeal as frivolous and the district court’s dismissal of Omran’s complaint both count as strikes under the Prison Litigation Reform Act. See Adepegba v. Hammons, 103 F.3d 383, 387-88 (5th Cir. 1996). Omran previously received a strike when we affirmed the district court’s dismissal of his civil-rights *133 lawsuit as frivolous in Omran v. Metrejean, 2015 WL 1508382, at *1 (W.D. La. Mar. 13, 2015), aff'd, 2016 WL 1391454 (5th Cir. Apr. 7, 2016). Because Omran has accumulated at least three strikes under § 1915(g), he is barred from proceeding in forma pauperis in any civil action or appeal filed while he is incarcerated or detained in any facility unless he is under imminent danger of serious physical injury. § 1915(g). As Omran is not proceeding in forma pauperis in the instant appeal, he is also warned that sanctions may be imposed in response to future frivolous filings.

APPEAL DISMISSED AS FRIVOLOUS; MOTION FOR APPOINTMENT OF COUNSEL DENIED; 28 U.S.C. § 1915(g) BAR IMPOSED; SANCTION WARNING ISSUED.
