Authorities say one person was killed when a helicopter crashed in central New Jersey.

The crash occurred shortly after noon Saturday in West Windsor, but it was not immediately clear what caused the accident. The victim, whose name was not immediately disclosed, is believed to have been the only person aboard the helicopter

Several witnesses reported hearing grinding noises and possible explosions shortly before the Aerospatiale AS355 twin-engine helicopter went down in a cornfield 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.

Vehicle traffic in the area wasn't affected by the accident, but West Windsor police were asking drivers to stay away from the area while the investigation was ongoing.
