Police in Macau staged a series of raids yesterday in the second joint operation in less than a week targeting organised crime gangs whose disputes have claimed 10 lives so far this year. Properties belonging to two of the enclave's reputed triad kingpins were understood to have been among those raided in the operation which began at 6 am and finished seven hours later. Police sources said neither of the suspected gang bosses was in at the time of the raids and by last night it was unclear how many people had been arrested or questioned. Armed with automatic weapons and wearing bulletproof vests, officers from the Judiciary Police and Public Security Police raided addresses in Macau and Taipa Island, seizing an unspecified number of documents and cars. The operation was led by Judiciary Police Director Dr Antonio Francisco Marques Baptista. During a search of a villa at Chok Wan, Taipa, detectives found 600 cases of contraband British tobacco, containing six million cigarettes worth more than $4 million.
