A man inside a stolen truck had guns, body armor and Molotov cocktails when police arrested him in Seattle on Wednesday night, officials said Thursday.
The identity of the 21-year-old Nevada man was not released, and officials said they didn't know why he was at the University of Washington, where he was discovered.
University police first encountered the man sleeping in the truck at the campus in Seattle on Tuesday evening, university police Chief John Vinson said in a Thursday news conference.
Vinson described the contact as a "noncriminal" encounter; police left after questioning the man, who had no outstanding warrants.
The next morning, however, officials got an alert that the truck had been stolen from Montana on Monday, and when police returned to the site where the man had been sleeping, he and the truck were gone.
