A cleaner who appeared in court yesterday charged with robbing two staff at the Buddhist Cemetery at Chai Wan is alleged to be part of a gang that planned to steal valuables from a tomb and demand a ransom, a court heard yesterday. Wu Chung-shing, 37, entered no plea in Eastern Court to a charge that he, with others still at large, robbed two staff at the cemetery in Cape Collinson Road on January 29. Acting principal magistrate Colin Mackintosh adjourned the case to January 16 for further police investigation and legal advice. Prosecutor Chu Chung-keung said Wu had told police he had acted only as a lookout but had been aware of a plan to steal valuables from a tomb. He said Wu might face additional charges. The court heard that four men entered the cemetery's staff quarters late on January 29, armed with pistol-like objects and a beef knife, and claiming they were chasing a debt from a male staff member. Au Yeung-wai and Chan Wai-fong were tied up and blindfolded for two hours before they freed themselves, the court heard. Mr Au suffered minor head injuries. The victims then found one of the tombs had been tampered with and heavy equipment such as drills left at the scene. They were robbed of HK$50,000 in cash, four bottles of cognac, two mobile phones, one pen, one lighter, one jade pendant and one gold necklace, Mr Chu said. Wu was arrested at Tsim Sha Tsui police station on Monday. Mr Chu said the gang was believed to be a syndicate of Hong Kong residents and mainlanders.
