Chinese police have released human rights lawyer Teng Biao two days after men snatched him off the street and pushed him into a car without license plates.
The rights activist said Saturday that his abductors, who identified themselves as Beijing Public Security, put a bag over his head as they drove away.
Teng said he could not reveal details about his detention.
Teng's wife said Friday he failed to arrive at their Beijing apartment Thursday night after calling to say he was heading home from his office.
Wang Ling said she saw their car when she went down to investigate a noise, but did not see her husband. She said someone saw a man being dragged into a car and taken away.
Teng Biao is a close friend of Hu Jia, an outspoken civil rights activist who is being held on charges of subversion. Hu Jia spent much of last year under house detention.
Teng has also openly criticized China's human rights record as the Beijing Olympic Games approach.
