A group of property owners from Hong Kong petitioned Guangdong officials yesterday complaining about empty promises, an alleged attack by a property developer and unco-operative police officers. Sany Li Ip-king, spokeswoman for the Hong Kong Association of the Owners of Properties in China, said group members were not satisfied with their treatment. Ms Li, who owns three properties on the mainland, said group members encountered a series of problems before and after buying properties in 1993. The problems included developers selling apartments which were radically different from those advertised and selling flats which had not been built, she said. Wong Chek-Yat, owner of an apartment in Longhua township in Shenzhen, said he was attacked on Sunday by a developer and required five hours of surgery on a finger. Ms Li said five police officers at the scene refused to help group members call an ambulance or provide information on how they should report the case. Ms Li and 14 owners went to the Guangdong Public Security Department to file a report in the hope that the highest public security organisation in the province would help. A department official told the group that police officers they saw at the scene of the alleged attack were 'fakes'. 'They were probably only security guards who were hired by the developers,' he said. The group also petitioned the local Government in the hope that officials would help arrange a meeting with the developer next week to settle the dispute.
