A policeman used a fake identity card in his search for a man he says swindled him out of thousands of dollars. Marine officer Choi Ming, 37, pleaded guilty before Judge Fergal Sweeney at the District Court yesterday to using a forged ID card. Choi thought that by using the fake, bought in Shenzhen for $1,000, he would be able to ascertain the address and bank balance of the alleged conman, the court heard. The plan unravelled when a bank clerk spotted the fake ID card as Choi tried to open an account in the alleged swindler's name at the Bank of China in East Point, Tseung Kwan O, on June 29 last year. The sergeant, attached to the Marine East Division, was suspended after his arrest. His lawyer, Francis Yip, arguing in mitigation, said Choi had lost money in the property market in 1997. Then he met a businessman who told him he could make a handsome profit. Choi was promised a monthly profit of $7,500, but his money was lost and the businessman disappeared. Choi then went to Shenzhen to buy a forged ID card, issued in the businessman's name, Mr Yip said. The sergeant, knowing the man banked at the Bank of China, attempted to open a new account in his name. The judge said the fact that the defendant was a serving officer at the time aggravated the offence. 'Being a police officer is one of the jobs where a higher standard is required,' he said. Sentencing was adjourned to June 23.
