Four young men are being sought for a "wilding" spree last week in Portland, Ore., that involved assaulting and robbing several pedestrians, authorities say.

The Portland Police Bureau said the suspects – all believed to be in their early 20s – are wanted for a 90-minute assault and robbery spree beginning at 3:30 a.m. Aug. 12. Police say the suspects initially assaulted a motorist and newspaper deliveryman before robbing a gas station and beating another pedestrian.

The suspects were seen fleeing the scene in a red Chevrolet or GMC truck with Texas license plates, Portland Police said.
