Portland police arrest man after alleged 'Star Wars' light saber assault 

Police arrested a man who allegedly assaulted three people with a blue light saber at a…Toys R Us Wednesday night.
 A 9-1-1 caller . . . said the man was inside the store, swinging the "Star Wars" weapon of choice at customers, said Sgt. Pete Simpson, a spokesman for the Portland Police Bureau. While the caller was on the phone, the man then left the store — light saber in hand — and walked out to the parking lot.
 Officers tried to arrest the man, but he kept swinging the light saber at them, Simpson said. One tried to use his Taser on the suspect but the device didn't work.
 Another officer used his Taser and made contact, but the man knocked one of the wires away with the light saber . . .
 None of the victims of the light saber assault needed medical attention, Simpson said.
