A possible security concern prompted an emergency landing at LaGuardia Airport and the arrest of a passenger aboard the plane, multiple agencies confirmed Saturday.

The Federal Aviation Administration confirmed the safe landing of Republic Airlines Flight 4817 at the Queens airport around 3 p.m. following a “security incident.” All 80 passengers and crew deplaned the aircraft on the taxiway without incident.

The plane made an emergency landing after passengers reported suspicious behavior from someone on board the flight, a Port Authority spokesperson said. The passenger was taken into custody for questioning but further details about the behavior were not immediately known.

There is “no indication” of any substantial threat to the plane, the spokesperson confirmed. The passenger’s “suspicious” behavior prompted the plane’s pilot to radio ahead for an emergency and prepare officials to respond once the plane landed.

Video captured by a passenger and shared with NBC News shows firefighters attending to one person lying facedown on the taxiway.

According to the FAA, Flight 4817 departed Indianapolis bound for LaGuardia.
