Mainland and Macau also make big catches in joint anti-triad operation Police have dealt a heavy blow to triads in the past 11 days, with more than 1,600 arrests and the freezing of $90 million suspected to be the proceeds of crime. Officers also seized a 7.62mm hand-gun suspected to be related to a robbery in the New Territories, and arrested three people believed to be involved in robberies on the cross-harbour bus route 106. In the bus robberies, three salesmen were fleeced of $1.7 million in jewellery by thieves brandishing what appeared to be a pistol on double-decker buses running on the route since April last year. The most recent robbery was in March. Operation Glaring Sun, which started on June 8 and ended yesterday, was a joint effort with the mainland and Macau. Hong Kong officers raided more than 1,900 locations, busting 31 vice establishments, 30 gambling dens, nine drug dens and 61 pirate disc centres. Two undercover operations were launched to smash one particular triad gang and two vice syndicates. Police also froze $91 million belonging to the two vice syndicates. The Guangdong Public Security Bureau arrested more than 700 people and seized 39 guns in its region, while Macau police arrested more than 200 people involved in loan-sharking activities, theft and drug-related crime. Macau and mainland police also located five criminals wanted in Hong Kong. Fung Kin-man, chief superintendent of the Organised Crime and Triad Bureau, said the operation was intended to hit the triads' money-generating activities. He said the operation was a big success because of detailed planning and exchange of intelligence with Guangdong and Macau. 'Co-operation in the past showed that joint operations were the most effective way to tackle crimes committed by triad members,' he said. 'After investigations and gathering intelligence for a long time, we took action because we were confident that we had collected sufficient evidence.' Hong Kong police arrested 1,616 people, of which 533 were mainlanders. It is understood that the Wo Shing Wo and 14K triads were the main targets of the operation. The arrest of 40 suspected mainland prostitutes last Monday, who were kept in an open-air steel cage at Tsim Sha Tsui police station, was part of the operation. Officers also seized $11 million worth of illegal betting slips, 159,000 obscene or pirated optical discs, 3,000 litres of illicit fuel and 4.51 million contraband cigarettes. More than 30 offensive weapons, including knives and baseball bats, and an air gun were also found. Police also seized 123 grams of heroin, 212 tablets of Ecstasy, 180 grams of Ice, 1,104 tablets of midazolam, 70 grams of Ketamine, five grams of cannabis and four grams of cocaine.
