A FORMER police officer was yesterday convicted of accepting $180,900 from a man arrested in connection with a wounding case. Former station sergeant Leung Chi-kwan, 43, who served in the Royal Hongkong Police for 19 years, denied four counts of accepting advantages between April and July 1991. Eastern Court Magistrate Peter Line, finding him guilty on all counts, adjourned the case until July 2 for background reports. The court was told that on March 26, 1991, Cheng Kwok-tung, an acquaintance of Leung, was arrested by the District Anti-triad Squad of Wan Chai police in connection with a wounding case. Cheng was released on police bail the same day. The next day, Leung and Cheng opened a joint savings account. Cheng later deposited $180,000 into the account. On April 18, 1991, the police file on the investigation into the wounding case went missing and Leung was interviewed by police. He denied his involvement but the joint account was discovered. Leung said the money belonged to Cheng and was to be used to engage a solicitor. Inquiries by the Independent Commission Against Corruption revealed that on four dates between April and July 1991 Leung withdrew $180,900 from the account which was the total sum deposited plus interest. The court heard a substantial amount of the withdrawals was then paid into Leung's own personal account. Leung's counsel, Roderick Murray, argued that there was no evidence Leung had accepted an advantage. He said: ''All the Crown has proved beyond a reasonable doubt is that my client took the money out of the joint account. ''They can't prove he put it into [his own personal] account. ''It was not an advantage. There were legitimate reasons.'' Mr Murray asked the court to consider the delay between the offences and the trial. He said that until the time of the offences, Leung had had an exemplary career which was now in ruins.
