A GROOM whose stag do descended into chaos when a flight they were on was forced to make an emergency landing has condemned the way his friends behaved.

Joshua Mariner insisted he was not among six men arrested when alleged rowdy behaviour broke out on board and has branded the actions of those on board as “unacceptable”.

And he has vowed to take legal action against the German police who wrongly said in a statement that he had been arrested.

As reported, six of the 12-strong group could face fines of up to £20,000 after the plane had to make an unscheduled landing when trouble flared out onboard.

The group were on a Ryanair flight bound for renowned stag party destination Bratislava, Slovakia, to mark Joshua’s forthcoming marriage to fiancee Abi Whitmore.

But the pilot was forced to make a dramatic emergency landing in the German capital of Berlin and eject six members who allegedly became unruly on the flight.

Reports in Germany say the men became aggressive when they were refused alcohol – there are even allegations that one of the party stripped naked while on the flight.

Local police said the drunken Britons, aged 25 to 28, were met by officers upon landing at Schoenefeld airport near Berlin at 8.30pm on Friday.

They were taken into custody and held but were later released.

There were also conflicting reports as to whether Joshua, who is from Southampton and a former Bitterne Park School pupil, was among those taken off the flight.

A German police statement said the groom had been held but others posting on the Daily Echo website said that he had remained on the aircraft and continued his journey to Slovakia.

But in a statement released last night Joshua, 26, a self employed ceiling and partitions specialist, said: “The lads' behaviour was unacceptable and they will now have to suffer the consequences of their actions. It was reported by German police that I was one of the lads arrested which isn't true and I will be seeking legal advice as it has caused a lot of distress for me and my family."

Just hours before take-off they had posted pictures of themselves on social media raring to go.

The pictures were taken in a bar just hours before boarding the flight with them all wearing T-shirts with the groom’s face printed on the front.

The party had been aboard a 170-passenger flight travelling from Luton airport to Bratislava, named the best value city in Europe to have a stag party.

Each of those arrested now faces a fine of up to 25,000 euros (£19,700) for breaking Article 20 of Germany’s Aviation Security Act.

The plane’s remaining 164 passengers, including the other half of the stag do not involved in the incident, then continued their journey to Slovakia.

A statement from Ryanair said: “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.”

But last night a spokesman from German Federal police defended the force's previous statement and added: "According to my information on the weekend he was one of the six who were detained on Friday.”

“For German police it is only necessary that the six were behaving in a bad way.”
