An exporter of fluffy toys forged his mother's signature with the help of the manager of the bank he was defrauding to finance nights out on the town, a court heard yesterday. Cheung Ka-ming, 32, was sentenced to four years in prison in the District Court yesterday after he admitted he bribed a Hang Seng Bank credit manager, defrauded the bank and forged documents. Judge Michael McMahon also banned the BP Industrial Company executive from holding a board position in any company for the next five years. Cheung forged his mother's signature on a $1 million loan in November 1992. But his mother, Wong King-fung, said she forgave him and was in court yesterday to support her son. It was alleged Cheung hatched the plot with his long-time friend and Hang Seng Bank credit manager, Ho Kwok-leung. By last year he had cheated the bank of more than $8 million, including two loans totalling $7.2 million. The court heard the money was used to help pay off other outstanding loans and to keep Ho entertained. 'It was a bit like the tide going out. He had money chasing money to chase money,' said defence barrister Christopher Grounds. 'It was a gradual process. He was up to his neck in it.' Mr Grounds told the court Cheung could not keep up, physically or financially, with Ho's long nights out clubbing. Ho continued to go out alone, with Cheung footing the bill, the court heard. When he stopped paying, Cheung began receiving repayment demands from the bank - so he started to pay Ho's way again, it was alleged. Mr Grounds said Cheung was not personally pocketing money; a lot of it had gone back into his efforts to keep his failing business afloat. Cheung had tried to keep his creditors off his back by using each new loan to pay old bills. But 'the kite crashed', Judge McMahon said, and Cheung was arrested by the Independent Commission Against Corruption on August 15, 1995. Ho had been charged by the ICAC and was on bail, the court heard.
