THE family of the Hong Kong grandfather detained in Inner Mongolia for almost a year has lodged a complaint with the Legislative Council over the failure of the Government to help. Despite appeals to Tung Chee-hwa's office to help rescue Lok Yuk-shing, 63, from the run-down jail in Dongsheng, the Security Bureau has done nothing to lobby on their behalf, family members say. Lok has been detained since June 12 after an Inner Mongolian cashmere supplier failed to recover $4 million from his former employer. The Government has declined to intervene on the family's behalf because it says it would amount to 'interference' in mainland affairs. Lok's employer, Windon International Co, is owned by Lai Sun Group chairman Lim Por-yen. Mr Tung intervened to ask for Mr Lim's return to Hong Kong while he awaited trial on corruption charges in Taiwan last year. Ho Hei-wah, director for the Society for Community Organisation, who has been assisting the family, said 'the Government is not actively helping these people'. 'There have been no reports on the progress to the family members and no mention about through what specific channels the bureau has been in touch with [mainland authorities],' he said. 'The Government cites the principle of no-interference as the reason for not standing up for the detained man, but the principle is completely wrong. 'What is the Government's position when SAR people are in danger on the mainland and what is the agreement with the mainland counterparts?' A bilateral system should be introduced to allow mainland parties to chase people who are responsible for a commercial dispute. Mr Ho will assist Lok's family and two other families in similar situations to lodge their grievances with Legco's Secretariat Complaints Division on Tuesday. Among them will be Chan Chi-shing, 39, who paid $160,000 to buy his freedom last month from a detention centre in Jiangsu, where he was held for four months.
