A brutal clip has captured the moment a brawl broke out between three passengers on the platform of Northolt Underground station on Saturday (August 15).
In the shocking clip, a woman and two men are seen fighting on the floor between platforms as onlookers film the incident on their mobile phones.
Seconds later, the man in the blue t-shirt is pinned to the ground by the second male, while a woman appears to attempt to kick him in the head.
The woman shouts: "I'll f****** kill you, you f****** c***," while the second man goes to punch their victim in the face.
A series of expletives are exchanged between the three passengers before the man dressed in blue attempts to walk towards the stairs and away from the platform.
But, as he makes his way towards the exit, the man and the woman follow him, continuing to shout abuse.
Eventually, the clip cuts off as the three walk up the steps, away from the platform.
The fight is thought to have taken place on the evening of August 15, as the three passengers had stepped off a train at Northolt Underground station.
A British Transport Police (BTP) spokesman said: “We were called to Northolt Underground station at 10.40pm on Saturday, following a report of three people fighting.
“BTP officers attended the scene but all parties had left prior to their arrival.
"Enquiries are ongoing.
“Anyone with information is asked to contact BT on 0800 40 50 40.”
