Driver jailed two years for manslaughter says he thought the victim was going to attack his friend in convenience store A truck driver who accidentally killed a drunken man by punching him in the head after he thought he was attacking a friend was jailed for two years yesterday. In sentencing Borne Chung Pak-hei, 24, in the Court of First Instance, Mr Justice Gareth Lugar-Mawson said he had no excuse for lashing out at Ng Chai-nam, 54, in a Circle K convenience store in Wong Tai Sin. 'Nobody should attack a complete stranger, no matter how annoying they may be, in the way you did,' the judge said. 'The indications are that he was extremely drunk and was extremely annoying, but there is no indication that he presented a danger to anybody.' Chung pleaded guilty to one count of manslaughter. He was in the store with his married friends, Tang Chin-yan and Lau Ka-man, at 2.15am on October 1 last year. They were buying snacks to eat while they watched a soccer match on television. While the three were lining up to pay, Mr Tang asked Ng, who was drinking rice wine from a paper cup in the store, why he was staring at his wife. The court heard that earlier in the night Ng had pushed at shelves and shouted at cashiers in the store. Ng left after Mr Tang's comments but then returned and Chung saw him approaching his friends. Chung suddenly approached Ng from behind and hit him three times near his right ear, causing the victim to drop to the ground. The three then left the store. Ng was rushed to Queen Elizabeth Hospital, where he died from a haemorrhage in an artery in his neck. The court heard the fact that Ng was drunk may have contributed to his death. Because his neck muscles would have been relaxed, this would have increased his head movements, which snapped the artery. Chung gave himself up to police the next day after hearing news reports of Ng's death. Mr Justice Lugar-Mawson said he did not accept that Ng was about to attack Chung's friends. Evidence showed Ng had returned to the store to retrieve the paper cup he used to drink his rice wine. But Chung's early surrender and guilty plea were mitigating circumstances, as was the fact that no weapon was used. 'For this offence you have to go to prison. There is no realistic alternative,' Mr Justice Lugar-Mawson said. 'That is not only to punish you for what you did but also to send out a clear message to others in the community they should not, without reason, attack people merely because they are annoying.'
