Law enforcement is investigating a Nevada man who was driving a stolen pickup truck that contained a cache of dangerous weapons.

The man, who was arrested Wednesday night near the University of Washington in Seattle, had a stolen scoped rifle, a stolen shotgun, explosive devices and body armor in his possession.

"The suspect is in custody," University of Washington Deputy Police Chief Randy West said Thursday evening. "An investigation is underway."

Police haven't released the name of the 21-year-old suspect.

"We have no idea what his intentions are," University of Washington Police Chief John Vinson said at a Thursday afternoon news conference. "This is a very active investigation. We're trying to rule out everything at this point."

University of Washington police are working with the Seattle Police Department and the Federal Bureau of Investigation on the case.

University police first saw a man sleeping in a pickup truck near campus late Tuesday, Vinson said. They did a check on the license plate then, but didn't detect anything suspicious.

On Wednesday, police received notice that the truck had been reported stolen out of Montana. Officers were told to watch for the pickup and spotted it Wednesday night near the campus.

The suspect was taken into custody "without incident," and booked into the King County Jail, said the Seattle Police Department.

He wasn't formally charged with a crime as of Thursday night, West said.

The man was not cooperating with police, said Vinson, who also said that there did not appear to be any threat to the university community.
