Drunk tourists sparked panic as they fought in a red-light district in Thai 'Sin City' Pattaya.

Footage shows the chaotic brawl erupting along the Walking Street entertainment strip at 1 AM on April 27.

Several revellers appeared to be ganging up on one man wearing a black shirt and lying on the ground.

Their companions broke up the fight, with security officers also arriving to intervene. Police did not arrive and there were no arrests made.

Military top brass from Bangkok have been trying for several years to clean up Pattaya, dubbed the 'sex capital' of the world and a modern-day Sodom and Gomorrah, as they battle to kick out badly behaving Brits and Aussies, and turn the region into a family-friendly resort to tap into lucrative family markets in China, India and Russia.

However, they face an uphill struggle against its entrenched 24-hour sex industry and endemic corruption that allows it to continue unabated. The bars - many of which are run by British ex-pats and function as shop windows for cheap prostitutes - along with massage parlours and street workers are also a lucrative part of the tourism industry, which before the pandemic accounted for 21 percent of Thailand's annual GDP, generating 1.8 trillion baht (52.3 billion USD) in revenue.
