Five men and seven women have been arrested in connection with prostitution offences in Preah Sihanouk province.
Provincial deputy police chief Kol Phally said the group was detained after a raid on the Thav Hong Massage shop in Sangkat 4 on Monday.
Police found used and unused condoms in the shop.
“They illegally operated a prostitution business under the cover of a massage shop,” he said yesterday.
Most of the 12, who were Chinese, did not have proper documents to live in Cambodia, he added.
All are being held pending further investigation at the provincial police headquarters and are due to be sent to the provincial court today for questioning.
