Multiple rioters were arrested Saturday night in Portland, Oregon, after a protest near an ICE facility turned violent, injuring four officers.

The unrest followed a peaceful “No Kings” demonstration earlier in the day.

Police declared a riot after federal officers were attacked with fireworks, rocks, and smoke grenades, and property was damaged, Fox News has reported.

Three individuals were arrested, with more arrests possible as investigations continue.
