A Chinese father jailed after campaigning for the victims of a tainted milk scandal in 2008 says he has been freed on medical parole and regrets his actions.
A statement posted on Zhao Lianhai's blog says he does not want to have contact with anyone any more.
His child was one of 300,000 made ill by milk powder tainted with the industrial chemical melamine. Six other babies died.
When sentenced to two-and-a-half years in prison in November, Mr Zhao angrily denounced the conviction and stated his intention to appeal against it.
But the new statement expresses deep regret for his previous extreme opinions.
Two Chinese human rights groups say they fear Mr Zhao has been pressured into conciliatory statements in exchange for his release.
