MEMORANDUM Substantial evidence supports the determination by the Board of Immigration Appeals (“BIA”) that petitioners did not establish eligibility for asylum. Chavez-Joaquin has not established that any persecution he suffered in El Salvador was on account of a protected ground. See Cruz-Navarro v. INS, 232 F.3d 1024, 1029 (9th Cir.2000) (“Persecution occurring because a person is a current member of a police force ... is ‘not on account of one of the grounds enumerated in the Act.’ ” (emphasis added) (citing Aguilar-Escobar v. INS, 136 F.3d 1240, 1241 (9th Cir.1998))).
Substantial evidence also supports the BIA’s determination that petitioners have not demonstrated a well-founded fear of future persecution. Without more, the threats Chavez-Joaquin allegedly received from gang members do not rise to the requisite level for asylum eligibility. See Mendez-Gutierrez v. Gonzales, 444 F.3d 1168, 1172 (9th Cir.2006). Having failed to establish asylum eligibility, petitioners do not satisfy the higher standard required for withholding of removal under 8 U.S.C. § 1231(b)(3). Ramadan v. Gonzales, 479 F.3d 646, 658 (9th Cir.2007) (per curiam).
Substantial evidence also supports the BIA’s denial of relief under the Convention Against Torture, given that only a single, unsubstantiated assertion presented to the BIA refers to the likelihood of torture. See Villegas v. Mukasey, 523 F.3d 984, 988 (9th Cir.2008) (“An applicant for CAT relief has the burden ‘to establish that it is more likely than not that he ... would be tortured if removed.’ ” (quoting Al-Saher v. INS, 268 F.3d 1143, 1147 (9th Cir.2001)) (alteration in original)).
