Malaysian police are holding 136 Vietnamese women they rescued from a prostitution raid in Kuala Lumpur on Saturday night.
A source of Thanh Nien News in the capital city said the women are still staying at Kuala Lumpur police headquarter.
They are facing charge under the Anti-vice, Gambling and Secret Societies Act, the source said.
The women were among 184 foreign women aged 21 to 38 who were serving at a night club on P. Ramlee Street in Kuala Lumpur.
Others include 17 women from the Philippines, 17 from Uzbekistan, four from Indonesia, four from Thailand, four from Armenia and two from Russia.
Initial checks found 25 of them did not have a passport, which prompted the police to investigate them as human trafficking victims as well.
Roslee Chick, an officer of the Royal Malaysia Police, said the women were lured to Malaysia for well-paid jobs but ended up being forced into sex slavery, according to Vietnam News Agency.
The police have arrested two Malaysian men managing the club and 13 guards.
