Funerals for the three latest victims of Macau's triad war passed off peacefully yesterday but new police fears have emerged over the professionalism of their killers. Worries about the hitmen, almost certainly from the mainland, who shot the three 14K triad members on Sunday - have prompted a two-pronged security clampdown. In the enclave, extra protection has been ordered for senior police and government officials. Steps are also being taken by China to tighten security on the Macau border in a bid to stop hitmen slipping in and out of the enclave. Internal Judiciary Police reports reveal that the motorcycle gunmen who shot dead senior 14K triad Shek Wing-cheung and two of his associates, fired nine shots. None missed. Detectives say the accuracy of the shooting - carried out while the gunmen rode one-handed on their motorcycles on either side of their victims' car while it too was moving - marks it out as one of the most professional they have seen. Shek, 37, also known by the nickname 'Man Cheong' was a former police officer in Hong Kong. He held both Macau and Hong Kong identity cards but sources say most of his activity took place in the enclave. Judiciary Police Director Dr Antonio Francisco Marques Baptista's car is now protected by four armed, plain-clothes motorcycle outriders and he has a team of bodyguards whenever he leaves police headquarters. It is believed that at least one of Mr Baptista's sub-directors and several senior Macau officials have also been given bodyguards. The gunmen used Chinese Army-issue 7.62 mm semi-automatic pistols to shoot dead Shek, Fong Mou-hung, 33, and Lo Wing-hwa, 35. Investigators fear the killings - part of a bitter war between the 14K and Wo On Lok (Shui Fong) triad societies, will spark retaliation. Shek was the bodyguard and 'senior lieutenant' of the reputed leader of the 14K in Macau. His remains, and those of Fong and Lo, were removed from the Kiang Wu Funeral Parlour to the Hau Si Cemetery on Taipa Island in three separate ceremonies.
