Forty suspected triad members have been arrested in raids on a faction of the Wo Shing Wo triad society, which allegedly is the major seller of rave party drugs to young people in Tsuen Wan. A Form Three student and 15 teenagers aged between 15 and 17 were among the 40 people arrested. Officers have raided 50 locations throughout the territory since Saturday following a nine-month undercover operation. The alleged 24-year-old head of the faction and two office bearers were arrested. Police were still hunting 20 members of the triad gang. 'The core members of the triad gang are teenagers. They recruited mainly young people like students and school dropouts to sell rave party drugs . . . in discos, karaoke lounges and games centres in Tsuen Wan,' a police investigator said. He said at least 500 tablets of Ecstasy and ketamine could be sold in discos each night. 'Each tablet is worth about $100 but they are sold to teenage triad members at about $40 each. They could make about $60 per tablet if they find buyers. It is very attractive,' the investigator said. 'The triad gang began to expand its power about two years ago. They were reportedly involved in a series of fights with rival triad gangs in order to dominate the drug trafficking business in the district.' The gang surfaced after it smashed another faction of the same triad society about two years ago, said Superintendent Ma Siu-yip of the New Territories South crime region. He said the gang was also involved in drug trafficking, extortion, illegal gambling, manufacturing of pirated compact discs, serious wounding and assault. During the operation, a small amount of Ecstasy, an extendable baton, metal rods and about 10,000 pirated compact discs were seized. Thirty-four of those arrested were released on bail of $2,000 each. They must report back to police next week. The remaining six men were being detained for further questioning.
