A TEENAGER turned to crime in a desperate bid to pay for her studies. Form Six student Lau Pui-shan, 18, got caught up in a racket involving forged travel documents to earn money to buy textbooks and pay for tuition. She appeared at the District Court yesterday and admitted a charge of possessing forged identity cards. She was placed on probation for a year. Prosecutor William Stirling told the court Lau had met a woman named Fo Kei who suggested the scheme to her and introduced her to a man known as 'Boss'. 'Boss' told her she would get a flight to Japan and he would pay her if she gave two envelopes to a couple who would be flying on the same plane. On August 7 they went to Kai Tak airport and 'Boss' gave her two envelopes containing doctored Hong Kong identity cards, Japan Airlines tickets for flights to Tokyo, and 69,000 yuan (HK$64,200). He told her to give the envelopes to the couple when they were safely on the plane. But a check-in worker realised something was wrong, and the police were alerted. Lau was arrested and the envelopes were found on her. Juliana Chow, defending, told the District Court the girl committed the offence out of stupidity because she wanted to earn money to buy textbooks and pay for tuition which her family could ill afford. Judge Jackson said the girl had committed an offence which could have led to an immediate custodial sentence. But after taking her age into consideration, previous good character and her background, the judge said he was prepared to give her a chance. He accepted that the offence was an isolated one and believed Lau would not offend again. He said the conviction was sufficient punishment.
