Oklahoma City police arrested a registered sex offender who is accused of threatening customers at a restaurant and trying to steal a soda truck while wearing shorts that exposed his buttocks and genitals.

Dominick Christian Thayer, 39, was still in Oklahoma County jail today with bail set at $9,500, jail records show.

Police arrested him at Chili's, 5301 N Classen Blvd., about 1:15 p.m. Saturday on complaints of assault with a deadly weapon, attempted larceny of a motor vehicle, public indecency and inhaling a harmful substance.

An officer who had just finished his lunch was in the parking lot when he saw a shirtless and barefoot man walk into the restaurant, the report states. Part of the man's buttocks were exposed.
