Footage shows police escorting a handcuffed man off a British Airways plane, after a passenger allegedly became aggressive and violent.

The video, filmed at Heathrow Airport, UK on Friday after the aircraft landed, shows officers heading towards the back of the plane to apprehend a man, who is shouting and swearing as he walks off.

According to reports, a 21-year-old man was arrested in relation to the incident on board the flight from Dubai to London.

A man who helped the crew deal with the incident also claimed he was "bitten".

The filmer later wrote online: "There was a big disruption towards the end of the flight.

"I was sitting in the rear of Premium Economy, near the back curtain, and could hear a lot of shouting and what seemed like a struggle in the economy cabin."

"I peered through the curtain to see a man standing up on the seats and cursing and pushing other passengers," he continued.

"The crew were very quick to react and restrain the guy, as did other male passengers who pulled him to the ground before the disruptive passenger could be restrained properly.

"A large amount of police came on board to take the man off the plane."

++CLIENTS PLEASE NOTE: THIS VIDEO HAS BEEN EDITED FOR SWEARING BUT THE MAN IS INDENTIFIABLE++

A young guy was getting violent with fellow passengers on a flight on Friday 1st April from Dubai to Heathrow. There was a big disruption towards the end of the flight. I was sitting in the rear of Prem Economy, near the back curtain, and could hear a lot of shouting and what seemed like a struggle in the economy cabin. I peered through the curtain to see a man standing up on the seats and cursing and pushing other passengers. The crew were very quick to react and restrain the guy, as did other male passengers who pulled him to the ground before the disruptive passenger could be restrained properly. The crew tied him to a seat with plastic straps and also a seat belt that appeared to go around the back of the seat to hold him in. He continuously cursed and swore and everyone and lost it. Women with babies and young children scattered into our cabin when the fight broke out. He was yelling out things like, 'I'm going to kill you', which was pretty scary at one stage to hear when you didn't know what was going on initially. A large amount of police came on board to take the man off the plane. Our flight was given immediate landing access due to the incident as was announced by the Captain. Please note there is a lot of swearing in this uncut video.
