Rumors then spread throughout North Philadelphia that a pregnant black woman had been beaten to death by white police officers. Later that evening, and throughout the next two days, angry mobs looted and burned mostly white-owned businesses in North Philadelphia, mainly along Columbia Avenue. Outnumbered, the police response was to withdraw from the area rather than aggressively confront the rioters. Although no one was killed, 341 people were injured, 774 people were arrested and 225 stores were damaged or destroyed in the three days of rioting.
