TWO men yesterday admitted taking part in two multi-million-dollar armed robberies on a Central jewellery shop in which shots were fired at police. Ng Yuk-ming, 30, and Chau Sai-ming, 27, pleaded guilty before Mr Justice Chan in the High Court to two counts of robbery, two counts of possessing firearms and one each of using a firearm with intent to resist arrest and possessing arms and ammunition without a licence. Ng is to give evidence for the Crown at a trial, after which he and Chau will be sentenced. Senior Crown Counsel Mr Richard Donald said that in the first robbery on October 26, 1991, five men, four of whom appeared to be armed with pistols, entered the Chow Tai Fook jewellery shop in Queen's Road Central. A security guard was subdued, his shotgun seized and staff and customers ordered to squat down. While the robbers were taking gold, watches and jewellery, police arrived. One robber fired at the police and the gang then fled out of the back of the shop, the court heard. The gang then hijacked a car stopped at a red light outside the China Building. At the junction with Connaught Road the robbers fired at three policemen, hitting an inspector in the right forearm, Mr Donald said. The officer was in hospital for 14 days. The robbers abandoned the car in Gloucester Road and hijacked another vehicle by threatening the driver with what appeared to be a pistol. This car was later abandoned at the junction of Nam Shan and Police School Roads. The robbers got away with more than $20 million in goods, none of which has been recovered. The second robbery was on March 12, 1992, when five or six men entered the shop, subdued two security guards, produced what appeared to be pistols and ransacked the display cabinets, taking goods worth more than $12 million. When a police patrol arrived, three shots were fired at them but no one was injured, the court was told. Later that day, plain-clothes police in Chai Wan Road saw the two defendants and another man acting furtively. Police followed the defendants to Walton Estate, Chai Wan, and then stopped them. They were told to line up and were searched. But there was a struggle and the three suspects drew pistols, with Ng firing at the police. A woman passer-by was hit in the right knee by a suspect. The three ran off towards Chai Wan Park. Police reinforcements were called and the park was cordoned off. At 2.40 am Ng was found with a Chinese-made pistol and 18 rounds of ammunition. Jewellery stolen the previous afternoon was also found on him. Chau later surrendered to police. His pistol and further stolen property was found in the park. The third suspect has not been caught.
