SHOCKING footage appears to show the moment a woman is swung around by her hair and a passenger was hurled to the floor during a chaotic brawl on a train.
One video captured by a horrified bystander appears to show a melee on the Transport for Wales service from Cardiff Central to Merthyr Tydfil at 9.20pm on October 12.
Officers from the British Transport Police attended the train at Pontypridd following reports of a disturbance on board.
The footage, taken by a passenger in a busy carriage, appears to show a number of passengers in a heated exchange.
Multiple commuters push and shove each other while some made attempts to diffuse the situation.
Unfortunately the chaos escalates and two women appear to grab a fistful of each other's hair.

One passenger is seen being swung around by her curls during the video as shocked bystanders watched on.
Eventually, both women appear to release their grip as other passengers intervened.
But shortly after, another passenger can be seen falling to the ground into the toilet cubicle before the doors close as the carnage reignited.
Another man attempts to throw some punches into the air, although they do not appear to make contact with anyone.

The scene appears to momentarily calm before a disturbance continues between a smaller group of people.
It is unclear what started the dispute.
A spokesperson for Transport for Wales said: “Officers from the British Transport Police met the 9.22pm [Cardiff Central] to Merthyr Tydfil service at Pontypridd on Saturday 12 October following reports of a disturbance on board."
They continued: "The safety and well-being of our passengers is our priority and we will not tolerate any behaviour that compromises the safety of our customers.
“Passengers who experience any issues on the railway can speak to a conductor or, for more serious matters, text the British Transport Police on 61016 or call 0800 40 50 40.
"In an emergency, always call 999.”
