A Ryanair plane was diverted after a passenger allegedly tried to open the emergency doors in mid-air.
The flight from Bournemouth to Girona, Spain, was forced to land at Toulouse airport on Thursday following an alleged brawl involving several passengers.
Witnesses claimed the fight broke out after a man, who was allegedly drunk, exclaimed "I want to go" and headed for the door.
Passengers tried to physically restrain him as he allegedly spat at and threw punches at them.
He was eventually pinned to the floor with a seatbelt tied around his ankles, it is claimed.
Video footage shows the man, wearing a white T-shirt and orange shorts, trying to resist as 13 French policemen carried him across the runway at Toulouse.
Passengers were left in tears, with some allegedly suffering panic attacks during the ordeal.
The flight eventually continued to Girona, landing around two hours later than planned.
One witness said: "The whole event was very traumatic. The man had gone into the toilet and then afterwards, was trying to open one of the emergency exit doors.
"He then went to try the other, shouting 'I want to go'. That's when a huge brawl started with a lot more than one man trying to get him away from the doors.
"There was a big punch up and he then finally got taken down in the aisle and was pinned to the floor where they then managed to get a seatbelt extender around his ankles to stop him kicking."
Another passenger claimed: "They started brawling in the middle of the plane. It went on for about 30 minutes... it took about three people to restrain him.
"It was horrible, there was blood everywhere. There were people screaming and crying."
'He took him to the floor in military style'
Another witness said: "He tried to stand to go to the toilet while we were taking off. When asked to sit down, he shouted 'I need a p--- mate' but then sat down.
"Once in the air, he then stumbled to the front, trying to open the doors in a panic. He was totally inebriated and wanted to get off the flight.
"Two men tried to calm and restrain him but he started spitting and swinging for everyone, crashing into people. One big guy warned him he was going to take him down if he carried on and he did so he took him to the floor in a military style."
A spokesman for Ryanair said: "This flight from Bournemouth to Girona (4 Sept) was diverted to Toulouse after a passenger became disruptive onboard.
"Crew called ahead for police assistance, who met the aircraft upon landing at Toulouse Airport and offloaded this passenger before this flight continued to Girona.
"Ryanair has a strict zero tolerance policy towards passenger misconduct and will continue to take decisive action to combat unruly passenger behaviour, ensuring that all passengers and crew travel in a respectful and stress-free environment, without unnecessary disruption."
Bournemouth Airport declined to comment.
