A New Zealand tour guide arrested in Cambodia last month for what local police described as "pornographic dancing" has been released on bail.
Paul Brasch, 33, was among 10 people arrested at the pool party in the resort town of Siem Reap and charged with producing pornography.
The Phnom Penh Post reports the charges have been downgraded after no pornographic material was found and seven people have been released on bail.
A Ministry of Foreign Affairs and Trade spokeswoman has confirmed Mr Brasch was among those released.
Siem Reap is a popular tourist hub and base for exploring the temples of Angkor Wat in the Cambodian jungle.
A Cambodian Police website published photographs appearing to show some shirtless men lying on top of other men and women, who are clothed, in various positions on a floor.
The police website translation said those arrested ranged in age, from a 20-year-old Canadian woman to men in their early 30s.
According to the website, Lieutenant General Chea Heng said there were 77 tourists, 36 women, and 10 organisers who were dancing in a "pornographic mode".
The others arrested were British nationals Vincent Hook, 35, Daniel Richard Leeming Jones, 30, Thomas Alexander Jeffries, 22, Billy Stevens, 21, and Paul Francis Harris, 32, as well as Job Robertus van der Wel, from the Netherlands, David Nikolaus Aleksandr Ballovarre, of Norway, and Canadians Jessica Drolet, 25, and Eden Koazoleas, 19.
The expats and travellers were pictured in a group outside what appears to be a police station and websites also published pictures of the alleged offensive behaviour.
