Six women, believed to be guest relation officers (GROs) were among 20 individuals detained following a raid at a nightclub in Kuchai Lama.
It is learnt that the GROs raked in thousands of ringgit from their "clients".
Kuala Lumpur Immigration director Wan Mohammed Saupee Wan Yusoff said a search of the premises uncovered flower garlands priced between RM100 and RM2,000.
