"As officers went up to contact him, he was somehow able to get the torch into a sensitive area of the patrol car that it caught fire," Huserick said. 

Responding officers chased the man into a parking garage where they used a Taser to subdue him. One officer is believed to have opened fire but the suspect wasn't hit, the Seattle Police Department said.

Authorities searched nearby buildings to ensure no one else was injured.
