A BUSINESSMAN who tried to help a mainland woman emigrate illegally to Saipan, Micronesia, was jailed yesterday for 12 months. The plot was foiled when the woman, Guo Xiaoqin, 21, who had already gone through the immigration counter and was about to board a flight, met an airport supervisor who had barred her from a plane the previous day. Lau Yuk-kei, 37, was jailed for aiding and abetting Guo to possess a forged document, counselling and procuring her to deceive the Immigration Department, and a further count of possessing a forged document. He denied the charges. Guo is already serving a sentence after admitting possessing a forged certificate of identity. The District Court heard that Guo came to Hong Kong from her home in Fujian on a two-way permit on September 16. The woman, who had an aunt in the territory, heard she could get to Japan for 100,000 yuan (HK$93,000). Prosecutor Lui Kit-ling told the court that Lau, who had not met the woman before, prepared a forged certificate of identity after her arrival and told her to memorise it. On September 25, Lau took Guo to Kai Tak airport where she tried to board a flight for Saipan but with a stopover in Tokyo. A visa was not required for certificate of identity holders like Guo the court heard. But airport supervisor Wong Wai-keung was suspicious and advised the pair to delay their itinerary for one day. Lau then took the woman to a check-in office at Admiralty and got two boarding passes. To avoid suspicion, he also bought Guo a ticket to Guangzhou. The pair returned to the airport the next day. The woman was instructed to get clearance with her genuine two-way permit from the immigration control point. The fraud only came to light when they met airport supervisor Wong Wai-keung again before boarding the plane. Judge Surman said he was satisfied Lau met Guo at the airport, despite defence claims they came to Hong Kong together.
