AI is calling on the Chinese authorities to release five human rights activists recently detained in Shanghai, where they are reported to be held without charge. All were members of a Human Rights Association formed in Shanghai last year, which was refused legal representation. The five are: Li Guotao, chairman of the Association; Dai Xuezhong; Lin Muchen; Yang Zhou; and Wang Fuchen. There are unconfirmed reports of the arrest of another dissident, Yang Qingheng, in Shanghai on 10 May but no further information is available about him.
