A JEWELLERY thief was extradited to Hongkong in the first case of a criminal being returned to the territory from the fugitives' haven of Taiwan. In April 1988, jewellery broker Wong Tai-man, 35, had asked three wholesale salesmen to visit him and then robbed them and left immediately for Kai Tak airport and flew to Taiwan. Interpol tracked him down this January and he agreed to return to Hongkong. Wong, who is defended by Jean Hopkin, pleaded guilty to three robbery counts of jewellery valued at about $720,000. He will be sentenced on June 16 by Deputy Judge Daniell, who called for a background report. Crown Counsel Henry Mierczak told the High Court that Wong was the sole proprietor of the Yun Fat Trading Company of Albion Plaza, Granville Road, Tsim Sha Tsui. On April 26, 1988, Wong had appointments with three gems salesmen for 12.30 pm. 1 pm and 1.15 pm. Mr Mierczak said each had been asked to take a sizeable quantity of expensive jewellery. Wong gave his three employees the afternoon off. The first salesman, Law Kwok-wing, arrived at about 12.50 pm and was met by Wong. Mr Law put some gold ornaments on a desk but suddenly someone approached from behind, told him not to move and placed a knife at his throat. At the same time Wong took out a towel soaked in chloroform, but Mr Law pushed it away when he smelt it. Mr Law was tied-up, blindfolded and forced into another room, where his face was again covered with chloroform and he was forced to drink a liquid with a medicinal and alcoholic taste. Mr Law received cut fingers and grazes to his neck and face. The second salesman, Kan Kun-chee, arrived at about 1.10 pm and met Wong. Mr Kan took out some gold chains but was grabbed from behind by two men holding knives. The court heard that Wong put sticky tape on Mr Kan's mouth and eyes, and tied his hands. He was taken to another room and forced to drink some liquid, which made him feel sleepy. The third salesman, Kwok Ka-wai, arrived at about 1.25 pm and Wong opened the door. Another person holding a beef knife rushed into the office, grabbed Mr Kwok's neck and demanded money. Another person covered his eyes with sticky tape and his hands were tied. He was forced to drink a liquid, and then cotton soaked in something was put to his nose. None of the gold ornaments taken in the robberies has been recovered. Mr Mierczak said Wong flew to Taiwan at 2.40 pm that day. Under caution, Wong said he knew his accomplices planned to tie up the victims and rob them using a knife. He was responsible for watching and opening the door, he claimed. He also said he only got $20,000 of the proceeds. In Taiwan he worked in a restaurant. His wife and two children live in Hongkong.
