AN angry diner who demanded $20,000 compensation when he found glass in his noodles was yesterday found guilty of blackmail. Lee Wah-ka, 22, enforced his demand by smashing a glass and threatening to make the waiter eat the pieces. Judge Muttrie in the District Court said the victim, Fong Wing-wo, was very scared by the threat. Mr Fong told Lee, and the men with him, that he only had $5,000 which he put on a table. He said the balance would be paid later. But before the men could leave with the money the police arrived and arrested them. Lee was found guilty of blackmail. He had denied the charge. He was cleared of damaging doors at the restaurant and making off without payment. Prosecutor James McGowan said Lee complained of finding glass in his breakfast at Samuel's Restaurant, Ap Lei Chau, on April 10 last year. Lee was immediately offered another bowl of noodles. But the customers were not satisfied and threatened to notify Urban Services. When the group left the restaurant one of them smashed two glass doors. The judge said it was not known who was responsible. He said the fact that the doors were smashed suggested that Lee had genuinely found glass in his meal rather than putting it there himself in a bid to cheat the restaurant out of money. Later that day Lee returned to the restaurant with others. The defendant suddenly smashed a glass and told Mr Fong: 'Just try to swallow the glass fragments. If you can eat glass I will pay you $20,000.' Three other defendants, Lee Pei-keung, 19, Lee Choi-chun, 29, and Chung Fook, 24, were all cleared of blackmail after pleading not guilty. Lee Pei-keung was also acquitted of making off without payment. The defendant was remanded for sentencing to allow time for reports to be prepared.
