Authorities say they had been searching since Saturday for a Utah man who barricaded himself inside a fast-food restaurant during an overnight police standoff.

Cottonwood Heights Police Lt. Dan Bartlett said Wednesday that 36-year-old Joshua B. Williams is suspected of firing at a woman Saturday who was letting him stay in her house. Bartlett says the woman wasn’t hurt.

Bartlett says officers were in the Salt Lake City suburb of Magna, Utah, on Tuesday looking for Williams when he locked himself inside a Burger King bathroom. After a six-hour standoff, Williams turned himself in.

Bartlett says Williams will be booked on suspicion of unlawful detention and aggravated assault. He says it’s not a domestic violence case as Unified Police had said because Williams wasn’t in a relationship with the homeowner.

It was not immediately known if Williams has a lawyer to speak on his behalf.
