The mum of one of five Britons charged with producing "pornographic pictures" in Cambodia over a ‘sex position game’ says her son "did nothing wrong".
The five men are part of a group of 10 foreigners arrested on Thursday when officers raided a rented villa in the tourist hotspot of Siem Reap.
Police images show the clothed tourists appearing to pretend to perform different sexual positions on the floor during a party.
The Brits have claimed they are innocent and were not even pictured in the photos published online.
And one mum has even suggested that the tourists were pressured into a confession by police.
The group – including Brits Vincent Harley Robert Hook, 35, Daniel Richard Leeming Jones, 30, Thomas Alexander Jeffries, 22, Billy Stevens, 21, and Paul Francis Harris, 32 – was arrested by Cambodian police for what officials have described as "pornographic dancing".
Job Robertus van der Wel, from the Netherlands, 22, Canadians Jessica Drolet, 25, and Eden Koazoleas, 19, were also arrested, along with David Nikolaus Aleksandr Ballovarre, 22, of Norway, and Paul Martin Brasch, 32, of New Zealand.
They could face up to a year in prison.
A mum of one of those charged suggested the Khmer authorities pressured the group into a confession, adding: "He was doing nothing wrong, just having a good time and a drink."
She told MailOnline: "It is terrible to think of him being stuck out there and completely innocent."
Another mum claimed the tourists were told to sign court documents in the Khmer language without the help of a translator, and that one of the women was pressured to confess that she was in a picture of a woman exposing her breast, despite insisting that it wasn’t her.
She added: "They are scared out of their brains. They just did what they were told in the hope they [Khmer authorities] would say ‘oh, well we’ll get you all to sign these papers and nothing will happen’. They’ve signed these papers not knowing what they are."
Mr Stevens spoke to his mum Marci Harbour, 47, of Wadhurst, East Sussex, from jail. Afterwards she said she was "in pieces" and didn’t know what to do to help her son.
The group could face up to one year in prison, Samrith Sokhon, deputy prosecutor of the Siem Reap Provincial Court told Xinhua Net.
Most of the group were described by police as expats – but some were travellers, including a British tourist who claimed to have been in the country just two weeks when he was arrested.
The man said they were manning the barbecue at a villa party on Thursday at 4pm local time when police arrived and began picking out revellers from the crowd.
He said: "Honestly, it was really confusing. Everyone was confused. They raided, rounded us up – there was about 80 to 100 people at this party, some of them were tourists.
"There were about 30 of them police officers."
The man said the group believed the investigation was targeting tourists and expats in the south-east Asian country for wearing bikinis in public, and in relation to expat-run pub crawls in Siem Reap.
He said from their makeshift cell on Saturday that their families were "worried sick".
He added: "Our parents are doing what they can. It’s really just trying to keep a good vibe until we know the outcome."
They said they have been sleeping on the floor of an office at a police station in Siem Reap for days, and emphasised they had been treated well – saying officers were friendly and had brought them pizza.
It is believed the party was held by a group called Let’s Get Wet. An advert said tickets were £5 including a free drink. The events firm has held previous pool parties, according to a Facebook group showing tourists in bikinis and swim shorts.
An official Cambodian Police statement referenced pornography and dancing in publicising the arrests, naming 10 suspects, who had been charged following an investigation by the Office Combating Human Trafficking and Protection of Juveniles.
Police also released photos of people in apparent sexual positions, claiming they were taken at Thursday’s party.
The Foreign Office confirmed they were in contact with British nationals in Cambodia.
"We are assisting five British men arrested in Cambodia and are providing support to their families," a statement said.
