A British tourist made a humiliating walk of shame when he was arrested over a public sex act with a woman on a beach in Thailand.

The holidaymaker Loucaides, 23, from London, allegedly paid Nuchjaree, 61, to perform oral sex on him on the sand in 'p*rno Disneyland' Pattaya.

Shocking footage shows the intoxicated naked holidaymaker lying on the sand with his legs in the air as the pensioner prostitute set to work.

However, shocked onlookers spotted the couple and called the police in the early hours of Friday morning, January 23.

Taxi driver Somsak Pativat said: 'I thought someone had a medical problem at first, because they were in an unusual position. I pulled over and looked with another person. They made a recording of what was happening for evidence while I called over the police, as the station is very near.

'I was only driving someone from Bangkok, and I don't visit Pattaya often, so this is the first time I have seen people doing that on the beach. They both must have been very drunk, because they didn't care who was watching.'

The allegedly drunk Brit hurriedly put on a pair of shorts before asking the cops: 'What's wrong? What's the matter?'

Both were frogmarched to the police station and were charged with public obscenity, which carries a maximum fine of 5,000 baht (119 GBP).

Bizarrely, they claimed they were unaware that the public sex act was illegal.

Loucaides allegedly claimed in his defence to the police that he had ADHD, while Nuchjaree said she was 'a Singaporean student studying in Thailand'.

Police Major Chanan Kesornbua said: 'Both of the offenders were handed over to the investigating officer for further legal proceedings. The tourist was released when a fine was paid.'

Pattaya has become the country's flagship tourist destination, fuelled by the allure of bars, massage parlours, and cheap sex. It has been dubbed a 'p*rno Disneyland' by some Brits, who can find relationships and experiences not easily available in their homeland.

However, the region is now often seen as tarnishing the wider image of Thailand as a family-friendly holiday destination with stunning beaches, food and a rich history.
