A group of Indian tourists had a mass brawl with bouncers outside a nightclub in Thailand's notorious Sin City resort.

The holidaymakers and staff were seen locked in a messy punch-up in front of the Kamaa Club Pattaya in the early hours of Wenesday morning, June 14.

Footage shows the tourists being swarmed by the bouncers wearing the red uniforms emblazoned with the club's logo.

Realising they were outnumbered, they made a hasty retreat but were followed by the furious security staff, who sparked panic when they picked up a large rock and threatened to throw it.

The bouncers continued following the tourists across the street before returning to the nightclub.

Pattaya police officers said no complaints have been filed with them regarding the incident. They did not disclose a reason for the brawl.

Thailand's current military government has made efforts to clean up Pattaya after it was dubbed the 'sex capital' of the world and a modern-day Sodom and Gomorrah.

However, the entrenched sex industry and endemic corruption have proved difficult to tame in the once-sleepy coastal city.

A large number of British ex-pats have also set up bars in the sun-drenched resort, which has become an attractive place for pensioners to retire.
