Hong Kong Customs raided a logistics company in an industrial building on Wang Lung Street in Tsuen Wan on 8 May 2017, capping an investigation into a local drug trafficking syndicate that began early in the year.[1] Officers found a sea consignment from North America declared as personal effects and seized about 131 kilograms of suspected cannabis buds with an estimated market value of about HK$21.5 million, a record quantity for a Customs cannabis-bud seizure in the past decade.[1]

Officers kept the company under surveillance and arrested three local men, aged 26, 41 and 60, when they came to collect the consignment the same day.[1] Two of the men said they were unemployed and the third said he was a transportation worker.[1] Trafficking in a dangerous drug carries a maximum penalty of life imprisonment and a HK$5 million fine.[1]
