A CRAVING for citrus fruit ended in a 32-month jail sentence for an illegal immigrant. Ng Ching-shan, 17, pleaded guilty to burglary, possession of an imitation firearm and being in Hong Kong illegally. Ng broke into a house in San Tin, New Territories, on September 28, hours after swimming to Hong Kong from Shenzhen. He and four accomplices made off with $4,000, 1,000 yuan (HK$910) . . . and two oranges. Ng said the fruit represented his only share of the bounty. When San Tin resident Chan Ngok-yuen awoke he found someone had pried open the ventilation window in his kitchen. Mr Chan informed police after finding that his wallet had disappeared along with the fruit. Later that day, police stopped a light bus near Sheung Shui for an identity check. When an officer asked Ng to produce his card, he muttered something incomprehensible. A search revealed a plastic gun inside Ng's waistband. District Court Judge Longley yesterday rejected the defence counsel's argument that the gun was an obvious fake. 'To me it is frighteningly realistic,' he said.
