A helicopter crash landed on the roof of 787 Seventh Avenue in Midtown Manhattan on Monday afternoon, according to law enforcement officials. It was not immediately clear if that was the same person as the one reported as dead.
Nathan Hutton, who works in the building, told reporters about the chaos in the building as people tried to evacuate.
Andrew Cuomo said no one inside the building was injured, but he acknowledged the fears that the incident could have been worse.
The Federal Aviation Administration said in a statement: "We are gathering information about an accident involving a helicopter that crashed into a building in Midtown Manhattan". The fire on top of the building has since been brought under control.
When the helicopter hit the roof, there was a fire.
A senior FAA official told ABC News that it is investigating.
The small helicopter crash landed on the roof of a tower at 787 Seventh Ave., the AXA Equitable Center, between 51st and 52nd streets. There is no indication of a link to terrorism.
White House spokesperson Hogan Gidley said President Donald Trump has been briefed on the crash and "continues to monitor the situation".
"There was a flood of sirens outside and an announcement for us to leave the building".
"I want to just say, thank God for that.
What do you presume went through the minds of people in NY?"
Emergency responders are on scene. It appears as though the aircraft crashed into the office building's roof.
Helicopters are a regular sight in the air around Manhattan, and they have occasionally been involved in crashes.
