Two relatives of a senior Guangzhou official were murdered last Friday at his home inside the Guangdong party leadership's heavily guarded compound, it was revealed yesterday. Chen Kaizhi, chairman of the Guangzhou People's Political Consultative Conference, could not be reached for comment yesterday. But a source in the advisory body said the victims were Mr Chen's older brother, 74-year-old Chen Kaigui, and sister-in-law Guan He, 83. Guangzhou police have arrested two teenagers - Chen Guochan, 16, and He Sunfa, 15 - in connection with the case. Both suspects are from Mr Chen's home town of Yunfu in northwest Guangdong, and at least one of them is believed to be related to him. 'The case happened at Chairman Chen's home at about noon last Friday,' the source said. 'The motive was robbery. They did not expect anyone to be at home.' Officials contacted last night at the Guangzhou Government's Information Office confirmed the incident, but said they had no details. Guangzhou's local media did not carry reports of the murders yesterday. Mr Chen was visiting friends in Dongguan, where he worked in the mid-1980s, at the time of the murders. He found the bodies when he returned home at 8.50pm, the source said. According to the source, the two suspects were arrested by police at about 7am the next day. 'They were found with 30,000 yuan (HK$27,900) worth of cash and valuables taken from Chairman Chen's home,' the source said. He added the suspects also were found with a key to Mr Chen's home. The Guangdong Communist Party Committee compound on Xinhepu Road, in Guangzhou's eastern Dongshan district, is regarded as one of the most secure places in the city. It contains the offices and homes of many senior provincial and municipal leaders, including Politburo member and Guangdong Party Secretary Li Changchun. The suspects allegedly used their connections to Mr Chen to enter the compound, saying that they were visiting him for the Lunar New Year holiday, the source said. Next door to the compound is the headquarters of the Guangzhou Military Region Command, where thousands of PLA soldiers live and work. Yesterday, heavier security was evident in and around the Guangdong Party Committee compound. At 5pm, a group of about 50 People's Armed Police marched into the compound while about half a dozen security personnel lined the road outside. In contrast, there appeared to be no increase in security at the office of the city's People's Political Consultative Conference, a five-minute drive from the party compound. Mr Chen, 61, was a Guangzhou executive vice-mayor and member of the municipal party committee in the early and mid-1990s. He was appointed chairman of the conference in June 1998.
