Greater Manchester police have said a man has now been arrested on suspicion of making a hoax bomb threat.
A Qatar Airways plane has been escorted into Manchester Airport by an RAF jet after the pilot received information about a possible device onboard.
Qatar Airways said Flight QR23 was carrying 269 passengers and 13 crew members when the threat was received, and the airline "immediately took all the necessary precautions to alert British authorities".
Qatar Airways confirmed that the plane was an Airbus A330-300 traveling from Doha to Manchester.
Twitter user Josh Hartley, who appears to have been on the flight, posted pictures of the military jet escorting the plane.
Matthew Qox, who claims he was sitting next to Hartley on the flight, tweeted this picture of police appearing to escort a man off the plane once it landed.
Flights were reportedly diverted to Leeds Bradford Airport as a result of the incident.
An eyewitness told Manchester Evening News: “I saw the fighter jet come from nowhere on the heels of the passenger plane. It seemed really close and was incredibly noisy."
"I thought it was going to hit the plane. It was circling so close. The jet looked like it was following the plane to the airport.."
