Customs Drug Investigation Bureau officers intercepted and searched a man in Tai Po about 12.40pm on 4 May 2004 and found about half a gram of suspected cannabis in his possession.[1][2] They then searched his residence at Kam Shan Village, where they uncovered what Customs described as the first cannabis cultivating centre ever detected in Hong Kong.[1][2]

Officers seized 38 cannabis plants along with about 70 grams of cannabis and 1,000 cannabis seeds, a haul Customs valued at about HK$400,000.[1] Two men and a woman, aged between 29 and 39, were arrested in the operation.[1][2]

A Customs spokesman said the cannabis was believed to have been planted for self-consumption as well as for sale.[1] Planting cannabis carries a maximum penalty of a HK$100,000 fine and 15 years in prison under the Dangerous Drugs Ordinance.[1]
