TWO Hong Kong men held in a Ho Chi Minh City prison for allegedly forcing Vietnamese women into Macau brothels have asked diplomats to track down their wives in the territory. British consulate staff were finally granted a visit to Yuen Hok-yan and Fung Wai-keung after repeated requests to gain entry to Chi Hoa prison, the city's toughest jail. One official said the pair were fearful about their future but in good health and receiving the same treatment as other prisoners. 'They were very keen that their wives be informed and we have passed the message to the Hong Kong authorities, who are trying to find them,' one official said. 'They were certainly worried about what the future may hold, but we were unable to go into details of the allegations against them.' The pair, both 35, were arrested with Vietnamese partners more than a month ago in a racket being touted as a high-profile test case to warn foreign gangs. They have not been told yet of specific charges but have been warned they may be held for more than a year before trial while investigations continue. Ho Chi Minh City detectives have already been investigating for more than a year and have sent officers to Macau, where the men assembled brochures of Vietnamese women for a string of top nightclubs and karaoke lounges. They were arrested on tourist visas on one of several trips to the city while entertaining several Vietnamese gangsters and prostitutes, detectives said. Several women who escaped the gang have told police they were beaten and forced to sleep with dozens of customers. Yuen and Fung had used 'charming talk' to get the women to fall in love with them, promising them fortunes if they went to work as waitresses in the enclave. After paying for their own flights to Guangzhou, their passports were seized by Macau agents. They had to pay HK$30,000 for the right to get them back before serving out a six-month visa. State newspaper campaigns against the pair are under way, with police claiming the case as their strongest yet in a drive against the smuggling of Vietnamese women into the red-light areas of China and Southeast Asia. The women all left Vietnam with proper papers and diplomats are unsure exactly what charges the men would answer in court. In one of the first cases of its kind, Vietnamese man Le Thu Le was recently sentenced to 17 years' jail for tricking friends to let him take their daughters to China to pick tea. He sold five of them to Chinese men for US$400 (HK$3,096) each. One girl escaped to raise the alarm. Another girl killed herself.
