COLUMBIA, Mo. (AP) — Authorities have arrested a Columbia man who’s accused of impersonating a Louisiana sheriff’s deputy to avoid arrest.

Reports say 29-year-old William Broadus is charged in Boone County with possession of a controlled substance. No attorney is listed for him in online court records.

The probable cause statement says Broadus caught the attention of a Missouri State Highway Patrol trooper by driving a car without a license Sunday afternoon. Broadus says he hadn’t registered the car after buying it a few months earlier and that he was on his way to buy drugs.

The statement says Broadus told the trooper he was a law enforcement officer and showed him a Louisiana parish sheriff’s badge. But the statement says he couldn’t explain what agency he worked for.
