"There was at least 75 people on the street acting disorderly. There were many fights, and most of the individuals in the crowd were females," Philadelphia Police Chief Inspector Scott Small said to NBC10.

Twenty PHA and Philadelphia police officers arrived to stop the fighting, which resulted in one PHA officer, 25, falling to his knees, blinded from pepper spray, Fox29 reported. He was treated at Temple University Hospital and later released.

"He was sprayed with pepper spray — went in both of his eyes. He was unable to see initially," Small was quoted by Fox29.
