PITTSBURGH (KDKA) – Pittsburgh Police are trying to identify two people involved in an alleged aggravated assault during a protest.

Police say they’re trying to identify both the suspect and the victim of an aggravated assault that happened on Penn Avenue during a protest downtown Saturday.

According to police, the man carrying the skateboard was seen using it to hit the bicyclist over the head.
