BEAVERTON, Ore. -- An Oregon man faces disorderly conduct charges after police said he brandished what appeared to be a gun outside a Beaverton middle school on Monday.

The man, identified by police as Dusten Jacob Williams, 20, also had painted his face to resemble the devil, officers said.

Police were called after several parents parked outside the Conestoga Middle School said they saw a man in face paint pull what appeared to be a handgun from his pants. At one point, they said, the man pressed the gun into the stomach of a student.

The school was locked down briefly as a result of the incident.

"Other witnesses said he 'worked the slide' back and forth and pointed it at the school pulling the trigger. The suspect eventually put the gun into the back of his pants and rode off on his skateboard," a press release from the police department stated.

Police arrested Williams on his skateboard a few blocks from the school.

"The suspect was armed with a sheathed knife and a realistic-looking black Glock replica Airsoft handgun, which fires small, plastic BB-like projectiles," police said.

Williams told police that he was just showing the gun to some friends and acknowledged that doing it in front of a school was "probably a bad idea."
