Mainlander who bit off passenger's thumb tip in scuffle jailed for 21 months A newly arrived mainland immigrant who felt he was being discriminated against vented his anger and hatred by biting off a man's fingertip in a scuffle aboard a bus in Sheung Shui, a District Court judge said yesterday. Wu Peng, 34, was convicted earlier of assaulting a bus driver and wounding a passenger after the driver told him to fold a baby stroller when boarding. He had pleaded not guilty to charges of common assault and wounding with intent. Wu, the father of a year-old boy, was yesterday jailed for 21 months and ordered to see a psychologist. District Court Deputy Judge Ada Yim Shun-yee said the defendant had shown no remorse for the bite which had caused permanent damage to the right thumb of his victim, Li Kan-cheun. Mr Li's thumb was broken in the attack. He spent nine days in hospital and had two operations, but the thumb's range of movement has been reduced and the tip is numb, the court heard. 'The defendant believed he was being discriminated against ... He accumulated hatred and anger. He said [in his sentencing reports] the bite was his only choice at the time. That shows he has no remorse for his actions,' the judge said. On May 26, Wu boarded a bus to Sheung Shui with his son, who was in the stroller. Driver Wong Sheung-ling told him to fold it up for safety reasons before she drove off. Wu complied after arguing with Mr Li. But he opened the stroller again and Ms Wong decided to call police and asked other passengers to get off the bus. When Mr Li and Ms Wong tried to stop Wu leaving the bus before police arrived, he pushed the driver to the floor and bit Mr Li. Psychiatric reports showed Wu suffered no mental illness. A psychologist's report concluded that the assaults were due to his inability to deal with interpersonal conflict, the court heard. Miss Yim took as her starting point a sentence of 30 months but reduced it by nine months on account of Wu's clear record and his mitigation. Wu spent 10 years working in Japan and came to Hong Kong last year to work as a language teacher and translator. Albert Luk Wai-hung, counsel for Wu, said in mitigation that his client gave up the right of abode in Japan and moved to Hong Kong to please his wife. But he had difficulty adapting to life in the city and, as he could not secure a full-time job, became a stay-at-home-dad, which he found stressful and frustrating. The language barrier also left him with no one to talk to. In the bus incident, he had felt he was being picked on because he was a mainlander, Mr Luk said. The judge said she could understand Wu had felt an affront to his dignity, but she could not comprehend his violent reaction. 'Someone was seriously injured [and the court is asked to believe] this resulted from the environmental circumstance and that society should be responsible for it. But was it not his fault?' she said.
