(CNN) Portland State University police shot and killed a man who was trying to break up a fight outside a sports bar early Friday, multiple witnesses told CNN affiliate KATU, sparking outrage and protests against the university's armed police force.

Witnesses said the man, whom they identified as Jason Washington, was fatally shot by campus police after a fight at 1:30 a.m. Friday outside a local bar.

The Multnomah County, Oregon, Medical Examiner's office also identified the deceased as Jason Washington. Portland police said in a statement there was an "officer-involved shooting" at that time outside the Cheerful Tortoise bar, but did not identify the person who was shot.

Witnesses told KATU that Washington was trying to break up a fight. During the scuffle, a gun fell out of his holster, witnesses told the news station, and when he reached for it, officers fired at him.

"From there it just kind of took a turn for the worst, and the good guy ended up getting shot," Keyaira Smith, who filmed the shooting, told KATU.
