The brutal melee shows around a dozen men trading blows in the car park of the Milla de Oro on the resort's Golden Mile
THIS is the shocking moment a brutal brawl erupts between two groups of drunken revellers outside a Spanish nightclub after a woman "flirted" with a rival's boyfriend.
The bloody melee shows around a dozen men trading punches and kicks in the car park of the exclusive Milla de Oro on Marbella's tourist-packed Golden Mile.
Two men were knocked unconscious and one victim was repeatedly pummelled in the head as he lay helpless face down on the concrete.
He was dragged off the pavement so his attacker could continue to pound his "lifeless" body more easily.
When police arrived they found the tarmac covered in blood but the attackers gone.
An investigation is now under way to track down the thugs.
The disturbing footage was captured by a bartender on his mobile phone as he went to take the bins out.
It shows several women caught up in the chaos as the two gangs swing and kick out ferociously at each other.
A man in a burgundy shirt is knocked out cold with a single punch and a bottle is heard smashing on the ground.
Then a man in a white shirt is floored and two attackers punch and stomp him while he lies sprawled.
When another man bravely steps in to try and break it up he is also brutally beaten down.
A man and a woman are then seen dragging one of the casualties to safety by his outstretched arms.
Two women can be seen crying in horror with their hands covering their faces as they rush towards the nightclub, while staff frantically call the police.
El Periodico reports that the violence erupted after a woman flirted with a man from the rival group in front of his girlfriend in the club.
Other reports say witnesses heard her call him "handsome", sparking the row.
Some outlets say the people were involved are Spanish, others say Costa Rican.
One man is still being treated for his injuries at Hospital Costa del Sol.
The nightclub told the Malaga Hoy newspaper that the premises had been shut for an hour when the fight broke out.
None of those involved had been inside the club, it's claimed.
Marbella is a top Spanish resort for Brit holidaymakers and features regularly in the reality show TOWIE.
