PITTSBURGH (KDKA) – Pittsburgh Police are working to identify a man they suspect threw rocks or bricks at officers during demonstrations downtown.

Pittsburgh Police released photos of the man on Monday. They believe he threw rocks or bricks at officers on Fifth Avenue and Smithfield Street during protests downtown May 30.

At the time he was captured on camera, he was wearing a black shirt, a black jacket, a black hat and green pants.

Peaceful protests the Saturday following George Floyd’s death turned violent after they were “hijacked,” Pittsburgh officials say.
