A movie extra posing as an anti-graft officer tricked an accountant into handing over $578,700 to escape prosecution for 'corruption'. Lee Chi-keung, 37, was jailed yesterday for three years after being convicted of one count of deception and 11 of blackmail. He had pleaded not guilty. Deputy Judge Ian Candy said the victim, Lee Chi-lam, 63, was a truthful witness who did not exaggerate his court testimony. '[The victim] was naive and gullible to an extraordinary degree,' the judge said in sentencing Lee Chi-keung. 'You preyed on his weakness for a protracted period to deceive him and squeeze from him a considerable amount of money. 'The fact that, contrary to all common sense, [Mr Lee] went along with all the arrangements without informing the authorities or consulting a lawyer or without seeking to discover the identity of the person to whom this money was paid, seems amazing,' Deputy Judge Candy said. Earlier, prosecutor John Marray told the District Court that the defendant repeatedly called the victim's office to solicit payment between April 1993 and November 1995. In order to confuse and deceive the victim, Lee Chi-keung had used different names and voices. At one stage, Lee Chi-keung posed as a civil servant seeking a donation to help the Inland Revenue Department publish a journal. The victim paid the 'donation'. Then Lee Chi-keung, posing as an Independent Commission Against Corruption officer, told the victim the donation amounted to perverting the course of justice. He told the victim that, in order to avoid arrest and prosecution over the donation, he would need to pay a bribe either to an ICAC officer or to a Department of Justice lawyer. The victim eventually handed over $578,700 to Lee Chi-keung, either in cash or deposited directly into his bank account. In December 1995, after finally running out of money, the victim went to the police. Under caution, the defendant admitted using the money for a shopping spree and that he gambled away $500,000 in Macau.
