WEST WINDSOR, N.J. (AP) — Authorities say a helicopter has crashed in central New Jersey, but it's not known if anyone on board was killed.
The crash occurred shortly after noon Saturday in West Windsor.
Several witnesses reported hearing grinding noises and possible explosions shortly before the crash occurred in a wooded area near Route 1 and Quakerbridge Road in the Mercer County community. Authorities say the helicopter burst into flames upon impact, but no one on the ground was injured.
The cause of the crash was not immediately known, and it was not clear how many people were aboard the helicopter.
Vehicle traffic in the area did not appear to be affected by the accident, but West Windsor police were asking drivers to stay away from the area.
