A blind activist opposed to a violent birth-control programme in a Shandong city was released on Wednesday night after being 'kidnapped' in Beijing on Tuesday. Chen Guangcheng , 33, yesterday said the detention by the Linyi city government would not deter him from trying to help local victims seek justice. 'I'm not worried because I have not broken any laws,' Mr Chen said, adding that Yinan county police arrested him. 'They just want to keep our mouths shut so they can cover up their deeds,' he said, referring to 'study sessions' endured by women who refused abortions or people who associated with women illegally pregnant with a second child. Mr Chen said he was told by Liu Jie , the city's vice-mayor: 'What you reflected is good. But it should be undertaken through proper legal channels and not exposed to foreign media.' In July, Mr Chen helped Washington Post journalists report on a violent birth-control scheme.
