Shocking footage shows a gang of thugs punching a lone man to the ground before repeatedly kicking him in a vicious assault along London's Southbank which ended with a 17-year-old being arrested for carrying a combat knife.
The massive brawl on Saturday night was filmed by passers-by as they saw one man in a red jumper being crowded around by a violent mob.
One thug in the crowd can be seen pointing in the lone man's face, before another comes in from the side and repeatedly lands punches on the victim's face.
As he throws his arms out to balance himself, the mob grabs hold of him and kicks him to the floor.
Two men then stepped in and tried to calm the chaos, pushing the crowd back as the mob quickly grew.
They managed to break up the fight as concerned onlookers rushed to the victim's aid.
