Police have arrested a man they say stabbed another during a fight in downtown Portland on Sunday night.

Matthew Allen Davis

Matthew Allen Davis, 30, stabbed Aaron Moore, 22, after Moore intervened when Davis threw something at another person walking on Burnside Street, Portland police spokesman Sgt. Pete Simpson said.

When Moore intervened, Davis assaulted him, then stabbed him, Simpson said.

Simpson said other passersby stopped the fight and pulled Davis off Moore. One of them pepper sprayed Davis as they struggled to hold him down until police arrived.

Moore was taken to a hospital with injuries that were not life-threatening, Simpson said.

Davis was booked into the Multnomah County Jail on a charge of second-degree assault, as well as an outstanding warrant. Jail records show his bail is set at $250,000.
