A topless man has brawled with another passenger on a packed plane in shocking footage.
In the video, the shirtless thug appears to be trying to yank the other passenger out of his front-row seat on the Boeing 777 plane.
The altercation was said to be over a seat allocation.
Music can be heard playing in the background - suggesting the jet was still grounded on the runway at the time of the ugly scenes.
The argument intensifies and the seated passenger appears to slap the topless man’s face several times.
In response, the standing man throws three punches before one man grabs his wrist and pulls him away.
A second momentarily grabs the topless man’s neck and then tries to separate the two men with two others.
According to local reports, it took place on a flight operated by Biman Bangladesh Airlines, the national flag carrier of Bangladesh.
It is unclear if either man were arrested for the disturbance and what the row was about.
The video was shared on Twitter where it has gone viral with nearly 120,000 views and dozens of comments.
Twitter user Allwyn joked: “He's just asking for his shirt back.”
A second said: “Looks like the other pax tore his shirt. Also, this guy looks more helpless than aggressive.
A third said he had seen a "guy urinating on another passenger" on another flight.
One remarked: “It is observed that during air travels many people suddenly change their attitude and start showing extreme selfishness and meanness.
“Such bad attitudes result in in-flight problems. Alcohol is another reason.”
