The flight was travelling from Krakow to Dublin.
Two men have been arrested after a security alert on a Ryanair flight from Poland to Dublin last night.
According to Essex Police, the two men, aged 47 and 26, have been arrested on suspicion of making threats to endanger an aircraft and are currently in custody.
The flight was escorted to Stansted Airport by British fighter jets after a note claiming there were explosives on board was discovered in a toilet.
In a statement on Monday evening, Ryanair said: ”A Ryanair flight from Krakow to Dublin this evening (13 July) discovered a note in one of the toilets that involved a potential security threat on board.
“The captain followed procedure by alerting the UK authorities and diverted to the nearest airport (Stansted) where the plane landed normally, but was taxied to a remote stand where passengers disembarked safely.
“The aircraft and passengers are being checked by the UK police who will decide when they may travel onwards to Dublin on a spare aircraft. Passengers in Dublin waiting to depart to Krakow are being transferred to a spare aircraft to minimise any delay to their flight.
“Ryanair apologises sincerely for the delay and inconvenience caused to those affected by this diversion.”
