MEMORANDUM **

*697Lakhwinder Singh Ghara, a native and citizen of India, petitions for review of the Board of Immigration Appeals’ summaryaffirmance of an Immigration Judge’s (“IJ”) denial of his application for asylum, withholding of removal, and relief under the Convention Against Torture (“CAT”).

Petitioner’s CAT claim fails for lack of exhaustion and is accordingly dismissed. See Ortiz v. INS, 179 F.3d 1148, 1152-53 (9th Cir. 1999).

We have jurisdiction under 8 U.S.C. § 1252 over petitioner’s remaining claims. We review for substantial evidence, INS v. Elias-Zacarias, 502 U.S. 478, 481, 112 S.Ct. 812, 117 L.Ed.2d 38 (1992), and deny the remaining claims in the petition for review.

Substantial evidence supports the IJ’s decision that petitioner failed to establish past persecution or a well-founded fear of future persecution based on an enumerated ground. Petitioner was arrested after providing transportation to a suspected terrorist who was evading the police. Petitioner was harassed by rogue police officers years later because he was a witness in a lawsuit against the police. Because petitioner was arrested for aiding a suspected terrorist, and was harassed because he was going to be a witness, petitioner’s asylum claim fails based on a lack of nexus to an enumerated ground. See id. at 482-84, 112 S.Ct. 812.

Substantial evidence also supports the IJ’s conclusion that petitioner failed to establish withholding of removal because he did not show that it is more likely than not that he will be subject to persecution based on an enumerated ground. See Al-Harbi v. INS, 242 F.3d 882, 888-89 (9th Cir. 2001).

Finally, petitioner’s due process claim fails because he cannot show prejudice. See Cano-Merida v. INS, 311 F.3d 960, 965 (9th Cir. 2002).

PETITION FOR REVIEW DISMISSED in part; DENIED in part.
