A top customs officer with a history of long and meritorious service has been arrested by the ICAC for leaking information about the department's copyright investigations. The Independent Commission Against Corruption said yesterday that it had arrested six people in relation to the case, including a senior superintendent. Sources said the senior officer is Simon Wong Shiu-ming, from the department's administration and excise branch. Also arrested were the chairman and a director of a private detective agency as well as a senior executive and two employees of the International Federation of the Phonographic Industry. The graft busters have accused the customs official of taking bribes from the detective agency in return for supplying it with information about the department's investigations into music copyright infringements. The senior superintendent was also said to have been paid for referring businesses to the detective company, which was said to specialise in dealing with music copyright infringements. It is understood that the detective agency would use the information to approach music companies and offer them its services in seeking compensation from copyright violators in civil lawsuits. The ICAC said it believed the senior superintendent had accepted unauthorised loans of about $200,000 from the arrested music association executive. The anti-corruption agency said initial investigations suggested the loans were not related to bribery, but were nonetheless illegal. The senior superintendent was also said to have cheated the government by making false reimbursement claims on holiday expenses under the government's Long and Meritorious Service Travel Award Scheme. The ICAC said investigations into the case were continuing, and customs was fully co-operating. The Customs and Excise Department said last night that it would review procedures concerning the handling of classified materials if necessary. It also warned that it would launch investigations into any breach of conduct after the ICAC finished its investigations. The department said it could not comment about the specific case as it was under ICAC investigation. The six men, aged between 40 and 60, were arrested as part of an operation codenamed Jiujiang that began on Tuesday. The ICAC questioned about 60 people during its investigations.
