A CHINESE-Cambodian dual citizen was arrested Saturday at a hotel in Tuol Kork district and charged with cross-border human trafficking, Phnom Penh Municipal Police said Sunday.

The suspect, identified as 59-year-old Sitou Man, was apprehended when authorities raided his hotel room, where he was examining two women prior to sending them to China to work in the sex industry, Phnom Penh Municipal Anti-Human Trafficking and Juvenile Protection Bureau Chief Keo Thea said.

"This is a new success for our police department's effort to fight cross-border human trafficking and bring traffickers to answer for their crimes under Cambodian law," Keo Thea said.

The raid followed a lengthy investigation based on tips from Cambodians who had been victimised in the Chinese sex industry, he added.

Sitou Man is suspected of having been involved in trafficking in Cambodia for more than 10 years, police said, adding that he is a dual national who has lived in Cambodia since the 1970s.

Keo Thea said Monday that the suspect had been sent to Phnom Penh Municipal Court and charged with cross-border human trafficking.

Police are currently searching for other Cambodian women suspected of being victimised by Sitou Man in an effort to bring additional charges.
