Chinese activists detained, questioned in Shanghai

Two Chinese activists have been taken away by police in Shanghai as part of a crackdown ahead of the June 4 anniversary of the Tiananmen pro-democracy protests, a human rights group said Saturday. Mao Hengfeng, who has fought China's restrictive one-child policy, was "forcibly taken away by over 10 police officers" on Tuesday and is being held in a detention center, the New York-based Human Rights in China said in a statement. Xu Yongdao, who wrote a letter to UN Secretary-General Kofi Annan asking him to intervene on behalf of his jailed dissident son, was taken to a police station and warned against making further complaints, the group said. Authorities routinely clamp down on activists around politically sensitive dates, barring them from leaving their homes or temporarily holding them at secret locations.
