A SINGAPOREAN received a suspended sentence yesterday for his part in an illegal immigration scam, after he checked in to a flight to New York on behalf of another man. Fok Kum Seng, 41, was fined $5,000 after he admitted obtaining property by deception. Magistrate Gus Andree-Wiltens sentenced Fok to three months' jail, suspended for 18 months. The court heard Fok had been required to cancel his booking after he had checked in for the flight on April 2 via Seoul, transferring the boarding pass to a man with a forged passport and visa. Fok had said he had been offered a free round-trip air ticket to Hong Kong if he would check in for the United States flight and hand over the boarding pass. Fok had come to Hong Kong on March 29, and been told to meet a man called Ah-Fat. He was given an air ticket bearing the name Kum F. S., and had returned the boarding pass to Ah-Fat after checking in. Earlier that day, a Chinese man, Jiang Changyao, had been intercepted by immigration officers in a transit lounge. He had a Malaysian passport bearing his photograph but the name Kum Fang Sun, also with a forged US visa. Jiang, who was to receive the boarding pass, was given six months' jail for possession of false documents and false representation.
