Ben Wallace is facing a five-year felony charge of carrying a concealed weapon after they arrested him on suspicion of drunk driving early Saturday in the Detroit area.

Wallace told investigators the gun was his wife's, registered in her name and he does not have a concealed-weapons permit, according to the Bloomfield Township Police report released today.

Wallace said he threw it in a backpack on the rear passenger seat "because he wanted protection as he drove," from his home in Virginia to metro Detroit on Friday, according to the report.
