The first video footage from the scene of Monday's helicopter crash landing has appeared online.
Video footage apparently shot before the crash showed the chopper flying erratically just moments before the crash.
Police advised the public to avoid the area as firefighters deployed to the scene.
ABC News reported, citing a fire official, that one person was killed in the incident.
The building, located on 7th Avenue between 51st and 52nd streets, has been evacuated.
