Video of the shocking incident, which took place outside of Nottingham's Ink nightclub on Thursday, ends with the victims beaten unconscious in the middle of the road.

Footage of the brawl shows a rampaging bouncer knock out two men during the course of a fight that quickly spiralled out of control.

According to witnesses, chaos broke out in front of the city centre club, which was holding a 'student night' at the time.

The video shows one of the men violently knocked to the ground three times by the relentless blows before he falls face-first onto the road.

Dozens of onlookers can be seen screaming in the background as the fight unfolded. 

The huge doorman punches one of the men in the head, causing him to fall to the ground and hit a car on his way down. 

The young man then tries to get back on his feet but is quickly knocked back to the ground with another wallop from the bald-headed bouncer.

A friend of his then runs over to help and try his own luck - but he suffers the same fate and is sent flying into the first victim on the ground.

Once more, the first man gets to his feet to approach the security guard - and takes one final punch to the head before he falls face-first onto the concrete.

The injured man lies still on the street, while bystanders rush to help him.

One person watching on calls out "Someone call 999" while people surround the man.

It remains unclear what sparked the violent fight. 

A spokesman from the club said: "The police are aware of the incident and are investigating it further.

"We have spoken to the firm which supplies our security, informing them that the doorman involved in the incident should no longer work at the venue.

|We are co-operating with the relevant authorities to ensure the facts are established in a thorough manner."

A spokesman for Nottinghamshire Police said: "Nottinghamshire Police has been made aware of a video circulating online of an incident that is reported to have taken place in the Queen Street area of Nottingham city centre, either on the evening of Thursday, January 4, or the early hours of Friday, January 5, 2018.
