Trenton police have released officer body camera videos and police dispatch calls from the night of the shooting of the Art All Night arts and music festival.

At least 22 people were hurt when rival gangs got into a shootout in the early morning hours of June 17.

Much of the footage released by police shows the chaotic scene outside the Roebling Wire Works building where the 24-hour festival was being held.

Officers could be heard yelling at attendees to clear out of the area and to take cover. Other officers were going around looking for and tending to victims.

Several officers can be seen placing an injured person into a squad car to take to the hospital.

A majority of the victims were hurt outside the building, but several were found inside.

The Art All Night festival has been held in Trenton for over a decade without any incidents. But police say that this year rival gang members got into a dispute, resulting in gunfire.

Officials say that of the 22 injured, 17 people suffered gunshot wounds. The wounded included three suspects. Two of the suspects were hospitalized, and a third was shot and killed by police officers.

Investigators are reconstructing the crime scene to determine if any of the shooting victims were injured by police bullets. Four officers were placed on leave during the investigation.
