Passengers were successfully evacuated and the aircraft has been isolated. Five hundred people were on board the plane, according to WPIX-TV.

The New York Police Department's Bomb Squad, accompanied by bomb sniffer dogs, are traveling to the scene to search the Airbus A380 double-deck aircraft, Port Authority police spokesman Joseph Pentangelo told New York Daily News.

WPIX-TV reported that no suspicious article had been found, citing law enforcement. However, New York Daily News called the threat "credible," citing its own sources.
