Detroit Piston Ben Wallace is facing a five-year felony charge of carrying a concealed weapon after police found an unloaded pistol in a backpack in his car as they arrested him on suspicion of drunken driving early Saturday in Bloomfield Township. Wallace, 37, of Bloomfield Hills was in a 2007 Cadillac Escalade at 3 a.m. Saturday when an officer spotted the SUV driving erratically northbound on Telegraph Road at Long Lake Road. 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. Investigators found a magazine full of bullets for the .28-caliber FNH semiautomatic pistol in the backpack, too, according to the report.
