Authorities in suburban Detroit say Detroit Pistons centre Ben Wallace has been charged with drunken driving and unlawfully carrying a concealed weapon after a traffic stop.
Bloomfield Township police said Thursday that the 37-year-old Wallace was arrested about 3 a.m. ET Saturday after officers observed a Cadillac Escalade being driven erratically.
Police said they found an unloaded pistol in a backpack.
Officers say Wallace was given a blood-alcohol test and he was above Michigan's legal limit of 0.08 per cent.
Police declined to provide further details.
Wallace, who helped the Pistons win the 2004 NBA title, was arraigned and released on a $5,000 US personal bond.
His next court hearing is Monday.
An email was sent by The Associated Press seeking comment from a Wallace representative.
