Two senior officers received bribes from colleagues in return for leaking confidential questions ahead of promotional interviews, a court heard yesterday. Chief Inspectors Law Hay-chung and Law Hay-sing, brothers aged 41, were then said to have bribed Superintendent To Kin-chung, 49, with an expensive dinner and 'lavish night club entertainment' in exchange for him passing a candidate. To was the chairman of Police Sergeant Force Selection Board 'B' while Law Hay-chung was a member of board 'D'. The prosecution said the Law brothers had obtained $180,000 from three constables - Chu Chi-wah, Kwai Chun-wang and Wong Chi-fai - which the brothers shared with other officers. Law Hay-chung yesterday denied three charges of conspiracy to offer advantages. Law Hay-sing denied four similar charges. Both pleaded not guilty to a joint charge of conspiracy to accept advantages. To denied a charge of conspiracy to offer advantages. Between August and November last year, the Law brothers allegedly agreed to secure promotion for Chu and Kwai through the help of Sergeant Lam Ting-chung. Chu and Kwai, both 32, yesterday denied one charge of conspiracy to offer advantages while Lam, 38, denied two similar charges. It was claimed Chu and Kwai were briefed by Law Hay-sing on several questions that would be asked at their interview. Prosecutor Kevin Zervos said Chu gave $70,000 to middlemen, Inspector Leung Chuk-ming and Sergeant Hui Kwok-leung while Kwai paid the same people $80,000. Leung and Hui were sentenced to 15 months' jail in February after admitting taking bribes of $20,000 each and passing the rest of the $150,000 to the Law brothers, the District Court heard. Mr Zervos said a third candidate, Constable Wong Chi-fai, gave $80,000 in return for the Law brothers to solicit interview questions from To to secure the constable's promotion. But $60,000 was seized by the Independent Commission Against Corruption. The prosecution said that last October, Law Hay-sing also tried to obtain $20,000 from Sergeant Chung Kuen-wah in exchange for securing promotion for his son-in-law. But Mr Chung later said he did not have money and he was not approached again. The trial continues before Deputy Judge Stephen Geiser.
