A Sha Tin district councillor was sent to hospital after being assaulted during a dispute with a man in Sha Tin yesterday. Chan Kwok-tim, 50, was leaving a newspaper stall in the Sha Kok Estate shopping centre in Sha Kok Street when the incident happened just before 12.30pm. After buying newspapers, Mr Chan turned to leave but accidentally bumped into a man passing by, police said. The man, 36, accused Mr Chan of staring at him and not apologising for the incident. 'He reportedly rammed his head into the victim's forehead during the argument,' the officer said. It is understood that the man also punched the district councillor. Mr Chan, a director of a sewing machine company, called the police who arrested the man at the scene. Mr Chan was taken to Prince of Wales Hospital where he was treated and later discharged. His assistant said he was in good health. 'Our investigation showed that the two men did not know each other. No indication showed it was a revenge attack. The alleged assault was triggered by the bumping affair,' the police said. The suspect was still being held for questioning last night and no charges had been laid. Officers said the man is likely to be released on bail pending further investigation.
