A mother led her son into a police trap when officers raided the family home and found drugs stashed inside a porcelain cat, the High Court heard yesterday. Li Yau-lan said she knew nothing about the heroin but her son might be able to help. She paged him, asking him to return home. When he arrived 20 minutes later he found the flat full of police officers and he was arrested. Lin Man-king, 22, was jailed for six years when he admitted trafficking in 121 grams of heroin worth $250,000. Prosecutor Graham Goodman said police found some of the drugs hidden in a porcelain cat ornament on a shelf above Lin's bed when they raided the flat in Sau Mau Ping on January 24. When he arrived he was questioned by the police and he admitted the heroin was his. His family knew nothing about it. Lin pointed out to officers where further drugs could be found in the flat. Mr Justice Frank Stock said he did not accept Lin's claim that he was simply looking after the drugs for another man for $10,000.
