A coffin and hollowed-out concrete slabs were used to conceal computer products and cigarettes in two cross-border smuggling cases. A metallic coffin containing 600 central processing units, 600 random access memory sticks and 10 LCD monitors was found on a mainland-bound truck, customs officers said yesterday. Sha Tau Kok divisional commander Mok Shiu-kin, of the Customs and Excise Department, said the truck, declared as empty, was stopped for an inspection when it tried to leave Hong Kong via the Sha Tau Kok border checkpoint at 8.10am. An X-ray examination revealed the coffin contained five cartons of goods. The haul of computer products was worth about HK$600,000. Officers said some paper offerings were also found in the coffin. The 52-year-old Hong Kong driver was arrested and charged with attempting to export unmanifested cargo. He will appear in Fanling Court today. Mr Mok said the truck was owned by a local company and used to transport corpses for burial either in Hong Kong or on the mainland. In a separate case, customs officers arrested three men, including a mainlander, and seized HK$1.23 million worth of dutiable cigarettes in Fanling on Wednesday after a two-week investigation. The cigarettes were stored in Lau Shui Heung Road, according to a customs spokeswoman. The arrests were made when the three men, aged between 48 and 53, were seen at 3pm on Wednesday breaking some concrete slabs and removing cigarettes, said Ronny Ng Yan-kwong, deputy head of Customs' Revenue and General Investigation Bureau. Thirty per cent of the cigarettes were counterfeit. He said 224 concrete slabs had been used to conceal the cigarettes. Each slab was about one metre by 18cm and weighed 30kg. Customs officials said it was the first time they had seen such means used to smuggle goods. He said an initial investigation showed that the haul was smuggled overland from the mainland. The three men have been charged with dealing in dutiable goods. They will appear in Fanling Court today.
