Police took Liu Xiaobo away from his home late in the evening of 8 December 2008. This was two days before the official release of the Charter. Police also took away Zhang Zuhua at that time. He is another scholar who signed Charter 08. According to Zhang, the two men were taken by police because they thought Liu and Zhang were trying to get more people to sign the Charter. While Liu was kept alone in solitary confinement, he was not allowed to meet with his lawyer or family. He was allowed to eat lunch with his wife, Liu Xia, and two policemen on New Year's Day 2009. On 23 June 2009, an officer of the government in Beijing (the procuratorate) approved Liu Xiaobo's arrest on charges of "suspicion of inciting subversion of state power." This is a crime under Article 105 of the Law of the People's Republic of China. The Beijing Public Security Bureau (PSB) said in a press release that Liu had incited the subversion of state power and the overturn of the socialist system through methods such as spreading rumors and slander, using almost the exact words of Article 105. The Beijing PSB also said that Liu had "fully confessed."
