A SENIOR Customs officer allegedly offered a colleague $7,500 to help unmanifested goods through a border checkpoint, Fanling Court heard yesterday. Cheung Wai-kwong, 40, is charged with conspiring with Ng Sheung-chun and others to export unmanifested electrical goods and with offering Ng $7,500 to export the goods through customs at Lok Ma Chau. He denies the charges. The court heard Cheung approached Ng, then a Customs officer responsible for checking manifests, several times between February and October, 1992. Cheung allegedly told Ng he had been asked to ensure goods vehicles carrying unmanifested cargoes cleared Man Kam To or Lok Ma Chau without Customs and Excise interference. Ng agreed to help for $7,500, the court heard. It was alleged Ng arranged the smooth passage of a vehicle for Cheung knowing it carried unmanifested goods on October 4, 1992, at Lok Ma Chau. After the vehicle crossed without interference, Ng notified Cheung by leaving a message with Cheung's pager. The court heard that four days later, Cheung paged Ng and asked for his bank-account number in which Cheung deposited $7,500. The hearing continues today.
