Bo Xilai 'responsible for two more deaths' While the US consulate shielded Mr Wang himself from officers loyal to Mr Bo, the police chief's associates, and other members of the investigation team were captured. "At least seven of Wang's associates, including his driver, were arrested by Bo, and at least two were tortured to death," said the document that was read out, according to the former official. As one of the 350 or so members of the Communist party's Central Committee, Mr Bo was entitled to a personal security detail. He also lived on a military camp in Bagongli, a suburb of Chongqing, and had close ties to the People's Liberation Army. The former official said the details had been read to all officials and party members above county level in order to consolidate support for the party's decision to remove Mr Bo from power. Since Mr Bo's downfall, the China's state media has printed a stream of editorials calling for stability and loyalty to Hu Jintao, the Chinese president. "It is when they write that we should be strong and confident that you know there is little confidence," said a second official. Beijing is worried about the reaction of the people but actually they should not be. He revealed that propaganda work to unite Chongqing's administration had begun even before Mr Wang tried to defect. A few days before the incident, there was a conference for propaganda leaders, and they were told that in case of a major incident, the foreign media would try to sensationalise it. When I heard this, I suspected something was about to happen," said the official, who also asked not to be named. The alleged deaths of two of Mr Wang's aides could be part of the "serious breaches of party discipline" that Mr Bo is being investigated for. Meanwhile, both sources dismissed speculation that Mr Heywood and Mr Bo's wife were romantically attached. "If she had grown unhappy, she would have been careful to choose someone outside her inner circle," said one. They also said that Xia Deliang, the district chief in Nan'an, was not part of Mr Bo's inner circle. In recent days it has been suggested that Mr Xia may have supplied the cyanide that is thought to have been slipped into Mr Heywood's drink. The official is one of the scores of people who have been detained as the Chinese government deepens its investigation into the case. It emerged yesterday that two more members of Mr Bo and Mr Wang's close circle at the top of the Chongqing police force have also been arrested. Guo Weiguo, the vice bureau chief of Chongqing's Public Security bureau, is said to have supported Mr Bo in his attempt to stifle the murder investigation. Li Yang, the head of general team of criminal police, has also been removed. Yesterday (Thurs) The Times reported that Zhang Xiaojun, a member of the Bo household who has also been arrested for his alleged involvement in the murder, travelled with Mr Heywood on his flight to Chongqing a day before he died. According to the Times, Mr Zhang may have been put in charge of making sure that Mr Heywood made his appointment with the Bo family in Chongqing. On November 14, he was found poisoned at a private villa in the Nanshan Lijing Holiday Hotel, a secluded three-star resort on a forested mountain overlooking the city. Mr Zhang, who is under arrest, is thought to be around 30 years old and originally served as a bodyguard to Mr Bo's father, Bo Yibo.
