Taiwanese judicial authorities detained a man yesterday after he turned himself in over a vote-buying scandal blamed for the narrow defeat of an opposition mayoral candidate in Kaohsiung. 'We have decided to detain the suspect after questioning him over his alleged role in the scandal,' Kaohsiung District Court spokesman Chung Chung-hsiao said. The man, identified as Ku Hsin-ming, surrendered to prosecutors on Wednesday, saying he was responsible for paying supporters attending a campaign rally in Kaohsiung last Friday, on the eve of the mayoral election. Mr Ku told prosecutors he had hired two tour buses to take the supporters to a rally for a certain candidate and later gave each of the supporters NT$500 (HK$120) for their campaigning efforts, Mr Chung said. Mr Ku claimed he liked the candidate and decided to help him by mobilising support, Mr Chung said without identifying the candidate. Huang Chun-ying, the Kuomintang candidate who was narrowly defeated by Democratic Progressive Party opponent Chen Chu, was accused by Ms Chen of vote buying. But Mr Huang denied the accusation, saying he was being set up in an attempt to affect the election result. Mr Chung said Mr Ku admitted that he worked for another man, a 43-year-old businessman named Yang. Mr Chung said investigators had found that the businessman had left Taiwan for Hong Kong on Wednesday morning, before Mr Ku turned himself in. He urged Mr Yang to report to the prosecutors' office or face being subpoenaed. Taiwanese media, quoting unnamed prosecutors, said it would have been impossible for Mr Ku to pay off the supporters, because he was not rich and received a monthly salary of no more than NT$40,000.
