A flight from Krakow to Dublin was forced to land after a note was discovered in a toilet claiming there were explosives on board.
The Ryanair flight was diverted to Stansted Airport where Essex Police officers were carrying out checks.

A spokeswoman for the airline said: “The plane landed normally, but was taxied to a remote stand where passengers disembarked safely.”
