Video emerged out of Portland, Ore., hours after the Derek Chauvin guilty verdict that police said showed an officer being surrounded and then punched in the face by a masked individual dressed in black.

The Oregonian newspaper posted the video and reported that there had been a heated confrontation. The individual who struck the officer could be seen being shoved by another cop on a bicycle. The officer who was struck grabbed onto the individual as he fell and then other officers jumped piled on. The paper said one of its journalists took the footage.
