OFFICIALS in Pailin province have ordered the closure of 11 establishments in which customers were able to pay for sex, an anti-human trafficking official said Monday.

Nun Saroeun, deputy director of the provincial Anti-Human Trafficking and Juvenile Protection Department, said the owners of the establishments had been ordered to sign contracts on August 10 in which they committed to closing last Thursday.

"The police and my staff investigated to find sex services being offered at restaurants, massage parlours and karaoke places, and we found that there were 11 in total," he said, adding that they expected to find more during future investigations.
