Firefighters and the police converged on a plane that traveled from Indianapolis and landed at La Guardia Airport on Saturday afternoon after a “security incident,” according to a Federal Aviation Administration spokesman.
The plane landed shortly after 3 p.m. and all the passengers safely exited, said the spokesman, Steve Kulm.
The flight, a Republic Airways aircraft operating as American 4817, declared an emergency and landed “in response to passenger behavior near the end of the flight,” a Republic spokesman, Jon Austin, said.
“Upon exiting the active runway, the aircraft stopped on a taxiway and conducted a precautionary emergency evacuation,” Mr. Austin said. “Our crew responded to the situation in accordance with our procedures and with professionalism and a concern for safety of all aboard. Law enforcement and first responders met the aircraft and the passenger involved in the incident has been taken into custody.”
The flight had 76 passengers and four crew members, American Airlines said. There were no injuries reported for any passengers or crew members, the airline said.
The person who was taken into custody was not identified, nor was it clear what behavior had drawn attention.
A video taken from the tarmac showed emergency responders surrounding a man who was on his stomach as passengers stood nearby. In another video, evacuated passengers are told to “step back” and give responders and the man space.
The U.S. Department of Homeland Security and the F.B.I. did not respond to emails or phone calls on Saturday afternoon.
The flight took off from Indianapolis International Airport around 1 p.m., according to data from FlightAware.
