British brothers Alfie and Kenneth Springthorpe have been slapped with a £50,000 fine for fighting aboard a Jet2 flight after one brother urinated on the other. The incident took place last month on a flight traveling from London to Crete, according to Metro.

A fellow passenger on the flight who witnessed the ordeal said, “About two and a half hours into the flight I was waiting to go to the toilet and the older brother stood up but was so drunk he couldn’t stand, he needed the loo but in his drunken state peed over the younger brother who then hit him resulting in a full fist fight.”

Under the seats of the brothers, who are from the Sidcup area of southeast London, cabin crew discovered an empty bottle of Ciroc Vodka as well as another that was half empty. With the chaos the brothers caused, the pilot had to divert the flight to Corfu, where one brother was able to walk off the plane while the other had to be dragged.

Video footage recorded by another passenger shows one of the men being dragged down the aisle of the plane by police officers in Greece. In the video, the man is seen with his pants falling down, barely able to stand.

The other passengers on the flight were forced to wait to continue to Crete until the head of the cabin crew had gone to the police station and given a statement. For more than 200 passengers this meant enduring a delay of over three hours and 45 minutes.

“ has issued a bill for more than £50,000 to a pair of disruptive brothers, alongside a lifetime ban, after their aggressive and violent behavior led to a flight having to be diverted last week,” said Jet2 in a statement.

“Alfie and Kenneth Springthorpe, from Sidcup, displayed a catalog of appalling behavior onboard the aircraft which included causing damage as well as unacceptable levels of aggression and even physical violence.”

“As a result, the highly trained crew were left with no choice other than to divert the aircraft, which was flying from London Stansted to Heraklion (Crete), to Corfu so that police could offload them.”
