Benedict Iyerifama Siminalayi, a citizen of Nigeria, petitions for review of an order from the Board of Immigration Appeals (“BIA”) affirming the immigration judge’s (“IJ”) decision to deny his applications for asylum, withholding of removal under the Immigration and Nationality Act (“INA”), and withholding of removal under the Convention Against Torture (“CAT”). Siminalayi argues that the IJ made an improper adverse credibility determination, the IJ erroneously concluded that his abuse by the Nigerian police was not on account of political opinion, and Siminalayi had shown that it was more likely than not that he would be tortured if returned to Nigeria.

This court gives great deference to an IJ’s decision concerning an alien’s credibility. See Efe v. Ashcroft, 293 F.3d 899, 905 (5th Cir. 2002). Siminalayi fails to provide any support for his challenge to the IJ’s credibility determination. See Chun v. INS, 40 F.3d 76, 78-79 (5th Cir. 1994). Moreover, the IJ’s finding that Siminalayi was not subjected to persecution, and did not have a well-founded fear of persecution, on account of his political opinion (the only basis claimed by Siminalayi) is supported by the record. The IJ’s findings that Siminalayi did not qualify for asylum and withholding of removal under the INA are supported by substantial evidence. See Gomez-Mejia v. INS, 56 F.3d 700, 702 (5th Cir. 1995). Moreover, Siminalayi’s conclusional allegations regarding the likelihood that he would be tortured if returned to Nigeria are insufficient to show that a “reasonable adjudicator would be compelled to conclude” that the IJ’s denial of his CAT application was incorrect. 8 U.S.C. § 1252(b)(4)(B); see also Efe, 293 F.3d at 907-08.

Accordingly, the petition for review is DENIED.
