This is the moment a brawl broke out between a pub-goer and two "bouncers".
The shocking incident is believed to have taken place outside a Wetherspoons in Sutton at around 11pm on September 3, according to reports.
Footage of the fight showed two men, who are thought to be bouncers, restraining another man on the ground.
Moments later, one of the "bouncers" appears to punch the victim several times.
At least two people can be seen watching the fight unfold.
The downed man is later seen with a bloodied nose and face.
One witness even claimed the security guards "had the wrong bloke".
A Wetherspoons spokesman said: "Following a full internal investigation into the incident, with immediate effect, the two members of the door security team involved with the incident will no longer provide services to any J D Wetherspoon pub.
"The company will not tolerate the use of violence by door supervisors engaged at our pubs.
"The pub management team was unaware of the incident at the time as the door supervisors involved did not notify the pub manager on duty that it was occurring.
"Given that the matter has been referred to the police, we are unfortunately not in a position to comment further."
A spokesman for the Met Police said: "Police were called at 22:44hrs on Friday, 2 September following reports of a fight involving four men on Hill Road in Sutton.
"Officers attended along with the London Ambulance. One man sustained a head injury but refused medical attention.
"No offences were reported to officers and no allegations were substantiated."
It comes after a group of burly bouncers violently beat a young woman to the ground outside a Marbella bar as onlookers watched in horror.
The glamorous revellers were standing in front of Lemmon, a nightclub in the resort town popular among Brit holidaymakers, as they rowed with door staff.
During the hideous assault, the women desperately tried to cover themselves as their outfits slipped amid the ruckus.
One tourist draped in a pink dress, is seen flapping her arms towards the large man after he violently pushed her.

Another holidaymaker tries to stop her white dress hiking up as a bouncer lifts her up and moves her away from the bar - all while being watched by a rowdy crowd.
One of the security guards moves back into the shot before knocking the woman in a pink dress to the ground.
He then picks both her and a friend up before carrying them away, the MailOnline reports.
Meanwhile, another woman can be heard shouting: "What the f*** are you doing?"
The same woman is then hit in the face as the pink-dressed tourist is thrown back on the floor.
