A police helicopter crashed and caught fire Wednesday night near an active shooter incident in Flagstaff, Arizona, as officers responded to an officer-involved shooting, authorities said. The shooting suspect is now in custody, though officials have not released details on possible injuries stemming from either the crash or the shooting.

Flight tracking data identified the aircraft as tail number N56AZ, registered to the Arizona Department of Public Safety. The helicopter went down during the law enforcement response in the Railroad Springs neighborhood.

Earlier in the evening, the Page Police Department issued an alert urging residents to avoid the area and shelter in place due to an active shooter. That alert was later updated after the suspect was taken into custody.

“We have been advised the Flagstaff shooting suspect is in custody, however, a police helicopter has crashed near the incident location,” the Page Police Department said in a statement. “Please keep the Flagstaff community and law enforcement in your thoughts and prayers.”

The cause of the crash remains unclear. Authorities have not said how many people were on board the helicopter or their condition. Video circulating on social media appeared to show the aircraft spinning out of control before striking the ground and immediately catching fire.

Shots were reportedly fired around the time of the incident, but police have not confirmed whether gunfire was directed at the helicopter. Investigators are continuing to examine both the officer-involved shooting and the helicopter crash as the Flagstaff community responds to the dual emergencies.
