A MAN was knocked unconscious during a furious face mask row at a London train station.
Police are continuing to investigate after the victim, who asked to be named William, was punched by a fellow passenger at Clapham Junction station.
William later required hospital treatment for a severe laceration and stitches for a head wound following the brutal blow.
Along with a friend, William had been arguing with South Western Railway staff by the ticket barrier because one worker was not wearing a mask.
Footage taken by William's friend shows a man in a grey hoodie - who was also not wearing a mask - push a pram past the heated exchange.
William is then heard saying "you're not wearing one either" - though this was not directed at the man.
In response, the man turns around and walks away from his pram screaming "don't f****** start on me" before taking a swing at William and knocking him unconscious.
William is left bleeding on the ground as the man flees the scene with his pram and child.
A member of rail staff is then heard saying: "I told you both to go didn't I?
William said: "My friend asked one of the station staff a totally reasonable and polite question 'are you exempt from wearing a mask?'
"She'd snapped back saying: 'none of your business'.
"Admittedly I lost my temper a bit.
"It escalated into a row with other station staff... then you can see the rest... thug leaves the scene, staff do nothing.
