A MAN described by sacked ICAC deputy director Alex Tsui Ka-kit as a 'friend' has been arrested and charged with a string of offences including attempting to pervert the course of justice. Henfrey Tin Sau-kwong, 45, a former Customs officer and Independent Commission Against Corruption (ICAC) informant, was arrested with two other men in an ICAC operation resulting in seven charges. Earlier this year Mr Tsui criticised the Legislative Council's Security Panel's report on his removal a year ago which stated that Mr Tsui failed to safeguard the ICAC's integrity by secretly associating with Tin. Arrested yesterday with Tin were Yeung Kam-fai, 43, also a former Customs officer, and Chong Tsoi-jun, 49, a merchant. They were in ICAC custody last night and were due to appear in Western Court today. Tin faces one count of accepting $20,000 and one count of conspiracy to offer money to Customs officers in connection with the expeditious processing of export permits for cigarettes and other related matters. Chong is charged with two counts of conspiracy to offer money to Customs officers and senior officers of British American Tobacco Company (HK) Ltd. The three are jointly charged on one count of conspiracy to export unmanifested cigarettes and one count of conspiracy to defraud the Hong Kong Government over matters concerning the export of cigarettes. Tin and Chong jointly face one count of attempting to pervert the course of justice. The offences allegedly took place between March 1986 and June this year.
