A California Highway Patrol officer in south Orange County saw a man in a truck driving erratically about 11 p.m. Sunday and began to pursue the driver before the suspect eventually fled on foot, shirtless, with a gun to his head and pointed it at authorities at the 5 Freeway and Bandini Boulevard.

He then walked down the off ramp and into a building in the 7000 block of Bandini Boulevard, where he waved his gun at employees inside.

"While he was inside that building, he was brandishing his firearm at the employees in there," Los Angeles County Sheriff's Sgt. Bob Boese said.

People who were inside the building at the time were able to get out safely.

Officers and Los Angeles County Sheriff’s deputies surrounded the area trying to get the man to come out. A SWAT team also responded, along with a helicopter.

After speaking with officers for an hour, the man finally turned himself in around 8:20 a.m.

The freeway was shut down in the area until about 2:20 a.m. when all lanes were opened, the CHP tweeted.
