Police arrested two unemployed men, both 22, for trafficking dangerous drugs in Kowloon City.

Officers seized 29.6 kg of a substance suspected to be cocaine, 1.1 kilograms of suspected ketamine, as well as 14.1 kg of “Happy Powder”, a date-rape drug found most commonly in Hong Kong, with a combined market value of about HK$27 million.

After a tip-off, police stopped and searched a suspicious man on the ground floor of a tenement building on Junction Road in Kowloon City at about 8pm on Saturday night. He was taken to an unit in the building, where other suspects were found.

More than 2,100 cardboard drinking straws and a batch of packaging tools were found in the unit along with the drugs. Officers detained two men on suspicion of drug trafficking, and other men in the unit were also arrested for obstruction. The case will be heard at the Kowloon City Magistrates’ Courts on Monday.

Police urge the public to be careful when they are in bars or clubs, beware of gifts from strangers, and avoid leaving drinks out of sight to prevent drink spiking.
