A court in Cambodia has granted bail to seven people including four Britons who were held in the tourist town of Siem Reap on charges of making pornography. Another Briton and two others remain behind bars.

The 10 foreigners were arrested two weeks ago after a raid at a private villa as part of a local crackdown on “immoral behaviour”.

They were charged with “making pornography” relating to images that had been uploaded to social media to promote an event called Let’s Get Wet.

Duong Thavry, the head of the anti-human trafficking and juvenile protection department in Siem Reap, said they had been arrested because “these photos and videos are against our culture … It is very disrespectful and gives the wrong idea of our country.”

Paul Harris, 32, Vince Hook, 35, Thomas Jeffries, 22, and Billy Stevens, 21, have all been granted bail until another court case next week decides their fate. If found guilty they face a year in prison.

However, it is understood that the organiser of Let’s Get Wet, Daniel Jones, who defied police warnings not to hold the party, is still being held. Ouch Sopheaktra, another of the group’s lawyers, said he filed for bail on Monday for the seven who were released, judging that their alleged offences were minor, but had not yet decided whether to appeal for bail for the other three because their cases were “a bit more complicated”.

The arrests have been seen as part of a backlash against hedonistic tourists, and the tourist culture, which have become a divisive force in the town, adjacent to Cambodia’s most sacred site, Angkor Wat.

Siem Reap’s governor, So Platong, said he would invite every bar and club in Siem Reap to a session where the traditions and customs of Cambodia would be explained, and any venue that flouted them would be shut down.
