Since September last year, Organised Crime & Triad Bureau officers have infiltrated a triad-run syndicate that runs massage parlours suspected to be used for vice activities in Mong Kok.

The officers raided 16 locations - including 10 massage parlours - at about 7.20pm, arresting  47 men and 57 women.

Most of the women hold Mainland two-way permits while the rest are local or from Thailand. The arrested men are believed to be the massage parlour managers while some are pimps.

The operation is ongoing.
