One person is dead and another has been left critically injured after two helicopters crashed in a southern New Jersey town.

Police in Hammonton, New Jersey, responded to a report of an aviation crash at about 11.25am on Sunday, according to Denise Mazzeo, the town’s deputy municipal clerk.

Police and fire crews extinguished flames that engulfed one helicopter, Mazzeo said in a statement to the Associated Press.

One person was killed and another was transported to a nearby hospital with life-threatening injuries. Video from the scene showed a helicopter spinning rapidly to the ground.

The Federal Aviation Administration and National Transportation Safety Board are investigating.

The FAA has said the crash was a midair collision.
