Two police officers were arrested by graft busters yesterday on suspicion of corruption, the Independent Commission Against Corruption confirmed last night. The two were a senior inspector and a police constable from West Kowloon, sources said. Overall, the corruption watchdog was believed to have arrested about 10 people in relation to the case, with some of the arrested believed to have triad backgrounds. Two of them were arrested on a gambling cruise liner in Hong Kong waters, sources said. The two officers' alleged wrongdoing was believed to be related to a wounding case involving suspected triad members, they added. Some of those arrested were seen being taken in handcuffs to the ICAC's headquarters in Central for questioning yesterday. The commission said police and the Immigration Department were involved in the investigation. But since investigations were continuing, the commission was unable to reveal further details about the arrest, a spokesman said. The police and immigration did not provide any comments last night. Several police corruption cases related to vice operations were exposed by the ICAC last year. In November, four policemen and a former customs officer were convicted of running a brothel, perverting the course of justice and inciting others to rob. In the same month, the ICAC charged a police sergeant for allegedly tipping off a brothel ahead of anti-vice raids in Mongkok between August 2003 and May last year.
