After having reportedly organised more than a hundred "swingers" parties during the past three years, a British man was arrested yesterday along with his Thai wife at a Bangkok hotel. With them were five Thais and 16 foreigners allegedly participating in a wifeswapping party.

Christian A Richards, 54, has been charged with procurement and commercial sex advertisements. The parties are advertised through www.Bangkok.CraigsList.co.th where Richards' wife goes by the name of Duang. They charge each participant Bt3,000.

The "swingers caught in the raid were a mix of Americans, French, Indians and Chinese. The Tourist Police arrived at the hotel suite to find the party just warming up and discovered condoms, 30 Viagra tablets and pornographic movies.

The police caught Richards in January at a party for about 50 people in a Huay Kwang hotel area but he claimed it was a birthday party and charges were pressed.

Tourist police commander Archayon Kraithong said that the police investigation suggests such activities have been going on for three to four years, attracting 25 to 30 people from many countries to each party.

The police issued a warrant for Richards' arrest on February 1, 2009.

The foreign and Thai participants were released after paying fines, while Richards was still being questioned by police yesterday. If found guilty, he faces a jail sentence of up to 10 years or a fine of up to Bt20,000.
