A man has been arrested on suspicion of making a hoax bomb threat after military jets were called to escort a passenger plane to Manchester Airport.
The Qatar Airways plane was escorted in to land by the Royal Air Force (RAF) following information received by the pilot.
Greater Manchester Police said it was treating it as a "full emergency".
Armed police boarded the Doha to Manchester plane and arrested a passenger on board.
All flights in and out of the airport were suspended for about 25 minutes.
