Police took a Christian legal scholar and rights activist from his Beijing home for interrogation this week, along with his wife and young son, as the government's crackdown on the dissident community continues unabated ahead of next month's Nobel Prize awards ceremony. Dr Fan Yafeng , the leader of an unregistered house church and a rights lawyer group, said yesterday that about a dozen police officers took him from his home on Wednesday night and questioned him for five hours until 2am. The summons says Fan 'carried out activities in the name of social organisations'. Without his knowledge, police also took his wife and their three-year-old son back to the police station for interrogation shortly afterwards. They were released at around 1.30am. 'My son said later he was frightened,' Fan said. Police also confiscated Fan's house keys and mobile phone. He later found that his computer had been tampered with and suspected that police searched his home while the family was detained. Fan said the authorities were targeting him and his wife, also a Christian, because of the activities of his church and the rights lawyer group, as well as a Christian magazine they were running. A month ago, police raided the printing factory which printed the Holy Mountain magazines and confiscated all the copies that had been printed. The Communist Party permits worship only in state-approved churches. Fan, a legal researcher at the prestigious Chinese Academy of Social Sciences before he was fired for his rights activism last year, said police had stepped up harassment of his family since last month's announcement that dissident Liu Xiaobo had won the Nobel Peace Prize. Beijing says the award is a Western ploy to destabilise China. Fan says his front gate has been guarded by police around the clock since then and he had already been summoned twice by police this month while hosting Sunday worship at home. He said he had not been allowed out of his home for nearly a month. Fan said the authorities may be planning to jail him. 'I have been involved in rights activism for many years ... I'm mentally prepared for being put in jail,' he said. 'But the comprehensive crackdown on civil society, including churches and NGOs, does nothing to defuse the current political crisis.' A member of the Shuangyu police station, where Fan was detained, refused to comment. Since the announcement of Liu's Nobel award on October 8, dozens of his supporters have been subjected to various forms of harassment, including detention and house arrest. They say the authorities want to prevent them from travelling to Norway to attend the Nobel Prize ceremony on December 10. Fan is a signatory of Charter 08, a manifesto calling for democratic reforms and basic rights drafted by Liu.
