THE Attorney-General, a High Court judge and the Correctional Services Commissioner were among several prominent figures to receive threatening or offensive letters from finance company manager Wong Kwai-nam, it was alleged yesterday. Other targets of abusive mail included the judge's daughter, leading property developers, and senior prison officers, Western Court was told. Wong, 30, who faces a charge of conspiracy to blackmail barrister Gerard McCoy in a separate case, was making his first court appearance in relation to the new allegations. Meanwhile, his brother, Wong Kwai-fun, 39, also appeared in the court facing the conspiracy charge. Wong Kwai-fun is accused of having conspired with Wong Kwai-nam and a third man who still remains at large to blackmail Mr McCoy between August 19 and October 24 this year. In the new case, the younger Wong is alleged to have sent 12 offensive and libellous letters under false names to 10 eminent people in the Judiciary, the Correctional Services Department and the business sector between January and October. Wong Kwai-nam, whose pregnant wife sat in the public gallery, entered no plea to the charges. He faces 12 counts of sending prohibited articles by post and three of criminal intimidation. He is accused of writing an offensive letter to Correctional Services Commissioner Raymond Lai Ming-kee on January 4 and threatening to injure him. Mr Lai's wife, Ng Wai-lin, received a libellous letter from Wong the same day, the court heard. Prosecutor Arthur Luk said that three of Mr Lai's colleagues had also received letters between May 16 and August 4. The officers - acting Senior Superintendent Wong Wai-man, acting Superintendent Yeung Bing-wing and acting Principal Officer Ng Chi-leung - were all working in the Siu Lam Psychiatric Centre at the time. A colleague of magistrate Ian Candy, who is overseeing the current proceedings, was also alleged to have received threatening mail. The accused is further alleged to have sent three defamatory letters to High Court judge Mr Justice Wong and his daughter, Rosaline Wong Wing-yue, a practising barrister. He is alleged to have threatened to injure Mr Justice Wong in a letter to Ms Wong on October 2. Attorney-General Jeremy Mathews also received an offensive letter in October, said Mr Luk. Other distinguished figures who allegedly received letters were Chen Din-hwa, chairman of Nan Fung Group, and his daughter Chen Wai-wai. It was also alleged that Wong Kwai-nam had threatened to harm Chen Wai-wai, who is a director of Nan Fung Development, in a letter posted on October 11. Mr Candy remanded both brothers in custody. He ordered that Wong Kwai-nam make another court appearance on November 30 in relation to the new charges. The Crown said that the papers to transfer the new case to the District Court would be prepared by that date. At the same time, the blackmail case was to be sent to Eastern Court for committal proceedings to the High Court on January 3 next year. Wong Kwai-fun was taken from the court to custody with his hands shackled to his waist.
