A security guard was posted at an urn cemetery in Chai Wan last night after 43 niches holding burial urns were damaged. A worker patrolling the Cape Collinson Chinese Permanent Cemetery in Cape Collinson Road discovered the damage and called police at about 8.30am. Metal frames around the niches were removed or loosened but only one of the marble slabs covering them was broken, the Home Affairs Department said. 'The urns containing human ashes were not damaged or stolen in the incident. It is the first time there have been so many niches damaged,' a spokeswoman said. There had been no complaints from relatives of the deceased before the desecration about demands for protection fees. Relatives were asked to visit the cemetery and check the niches. A security guard will watch over the niches each night until the repair work is completed. Until now, guards have not been on duty at night. The board of management of Chinese Permanent Cemeteries would review the security measures at the cemetery and discuss who would pay for repairing the niches. A police investigator said the motive remained unknown but it was possible that it was an attempted theft.
