One man wearing a red shirt pushes his victim towards the tracks

British Transport Police on the hunt for everyone involved in the brawl

A violent thug is being hunted by police for charging into a man from behind and punching his friend unconscious in a brawl that spilled onto the railway tracks.

Horrifying CCTV footage from Birmingham's Jewellery Quarter station shows the attacker, wearing a red shirt, storming towards his first victim just before 11pm on June 11.

The man slumps to the ground, his head left hanging perilously out over the tracks.

A friend of the unconscious man then rushes at the aggressor, but fails to make a solid contact with his punch.

He falls off balance onto the tracks, where thankfully there is no train in sight.

British Transport Police say the two friends were waiting at the station when they were approached by four men, including the suspect in the red shirt.

Members of the gang started to argue with the pair, which led to the flare up.

In the disturbing CCTV footage the man on the tracks is eventually aided up to safety by one of the group.

But the friend, with long hair, walks back over to the man in the red shirt and the scuffle continues.
