Police arrested two men aged 28 and 33, plus a 30-year-old woman for alleged possession of illegal drugs in Tuen Mun in the New Territories in the early hours on Monday.

Acting on a tip-off, officers from Yuen Long police district caught two Pakistani men, one with a Hong Kong Identity Card and other an asylum seeker, together with an Indonesian woman also seeking asylum at a bus station in Po Tin Estate at 1am, Oriental Daily reported.

Officers arrested the trio when they got out of a taxi at the bus station and confiscated one kilogram of suspected cannabis resin with an estimated street value of HK$105,000 (US$13,456).

After an initial investigation, officers believe that the woman, who is seven months pregnant, was used as a decoy to distract people’s attention from drug trafficking, HK01.com reported.

Police also arrested the local taxi driver but believed that he may not be involved in the case.

One of the suspects has a triad background, Sing Tao Daily quoted a police source as saying.

According to the law, any person convicted of trafficking a dangerous drug could face a fine of up to HK$5 million and life in prison, while someone convicted of possessing a dangerous drug could face a fine of up to HK$1 million and up to seven years in jail.

A 24-year-old man was sentenced 18 years in prison by the High Court in October for trafficking 7.9 kilograms of methamphetamine for payment of HK$8,000.
