A Hong Kong woman who has accused mainland officials of illegally detaining her father in Guangzhou yesterday claimed a Guangdong investigator had tried to gag her. Joyce Chan Yuet-chun said the Guangdong officer, He Liang, who recently issued the warning to her via her lawyer, was the same man who met her in Hong Kong in 2001 to pursue her father's case without going through the proper channels. Hong Kong police are still investigating whether any mainland officers have improperly exercised their jurisdiction in the special administrative region. Ms Chan's father, Chan Tsz-cheung, 56, has been held in Guangzhou since October 2001 in connection with an US$800,000 indirect loan from a mainland-linked company, which Ms Chan says is a civil case that has already been settled by a Hong Kong court. Ms Chan said when Mr He recently met her lawyer in Guangzhou to discuss her father's case, she was warned not to make more complaints in Hong Kong. 'He Liang told my lawyer that I had created lots of public discussion on the case and they are facing tremendous pressure. He said I had complicated the case,' she said. Ms Chan said she would not bow to any pressure. 'It's my right. I have no choice but to continue fighting for justice as I don't think it would help the case either if I remained silent,' she said. Ms Chan said Mr He told her lawyer that he was an officer from the procuratorate, not the public security officer he admitted to her two years ago.
