This is the moment furious revellers attacked a group of Indian tourists who were allegedly harassing a dancer at a nightclub in Thailand.

The angry mob descended on the holidaymakers who had visited the Dhoom Indian Mujra nightclub in the Walking Street area of Pattaya on January 3.

The intoxicated tourists reportedly argued with club manager Chandrabhan Bharat Yadav, also an Indian national, after they were caught harassing one of the dancers.

As they were being escorted out of the two-storey building, one of the group struck Yadav with a beer bottle, causing him to bleed.

Shocked passers-by and staff saw the injured owner and immediately swarmed the alleged perpetrator.

Footage shows the chaos that ensued, with several people, including a dancer in a yellow dress, pummeling a man in a white shirt until he lay defeated on the pavement.

The clip also showed a man with a blood-covered face pointing repeatedly at the tourist, while another half-naked man was sprawled on the ground.

Police Lieutenant Colonel Pichaya Kheawpluang, Pattaya tourist police inspector, said: 'We dispatched officers to control the situation immediately after receiving the report on January 3 at 9:58 pm.

'We were informed that there was a brawl in Walking Street and four people were injured.'

The four wounded were identified as Yadav, and three tourists, Dahul, Suvima, and Sain, all 30 years old. They were taken to the Pattaya City Hospital while the rest of the group returned to their hotel.

Sukarat Kalra, a restaurant owner along Walking Street, said: 'I was the one who called the tourism police.

'The tourists were thrown out because they were molesting the Indian dancer.

'They were ushered out by the manager, but they hit him with a beer bottle. The employees and the manager's friends came to help him, and it escalated into a fight.'

The group was allowed to recover at the hospital and were advised to report to the police station soon after, but they failed to show up to the station. Neither party had filed a complaint with the police.

Officers later learned that the suspected troublemakers had already left the country.

Military top brass from Bangkok have been trying for several years to clean up the notorious 'sex capital' of the world - branded a modern-day Sodom and Gomorrah - to turn it into a family-friendly resort.

However, they face an uphill struggle against its entrenched 24-hour sex industry and endemic corruption that allows it to continue unabated. The bars - which function as shop windows for 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.
