A pilot was forced to land his plane in Berlin after a British stag party caused problems on board.
Newspaper reports in Germany said the Ryanair flight from London to Bratislava in Slovakia was forced to land in the German capital to eject the bachelor party.
Six members of the group were said to have become unruly during the flight, forcing the pilot to make an unscheduled stop in Berlin and remove the passengers concerned from the flight.
German newspaper Bild said the men became aggressive when they were refused alcohol.
Local police said the drunken Britons, aged 25 to 28 and from Southampton, were met by officers upon landing at Schoenefeld airport.
They now each face fines of up to €25,000 and civil claims from the airline.
A statement from Ryaniar stated: "This flight from London Luton to Bratislava (26 Feb) diverted to Berlin after a number of passengers became disruptive in-flight.
"The aircraft landed normally and police removed and detained these individuals at Berlin Schonefeld Airport.
"We will not tolerate unruly or disruptive behaviour at any time and the safety and comfort of our customers, crew and aircraft is our number one priority. This is now a matter for local police."
