TWO men involved in jewellery shop robberies were each sentenced to 12 years' jail at the High Court yesterday. Another man was also sentenced to 12 years after admitting conspiracy to rob the Edelweiss jewellery shop in Peking Road, Tsim Sha Tsui, in March last year. Tse Sui-keung, 33, also admitted possessing a gun with eight bullets. Cheung Man-kwon, 25, pleaded guilty to two robberies in October 1989. Defence counsel Munira Moosdeen said her client had played only a secondary role and did not realise arms were to be used. Cheung committed the offences because he had borrowed $100,000 from a loanshark, counsel said. Yau Sun-choi, 25, changed his plea to guilty in one 1989 robbery charge towards the end of a trial and another three counts of robbery were left on the file. Duncan Percy told the court that Yau was in jail serving 121/2 years' for firearm and robbery offences committed after the 1989 robbery. Keith Oderberg said Tse, a delivery driver, was supporting his wife, two children and his elderly parents. At the time, his van was off the road, his wife was pregnant and his father was ill. He was desperate for money and agreed to take part in the robbery, then changed his mind and it was called off. He had pleaded guilty and asked for a chance to reform. Deputy Judge Gould sentenced Tse to four years' jail for the conspiracy and eight years' jail for possessing the firearms.
