Prominent Chinese dissident Hu Jia has been released from prison and reunited with his family, his wife says.
Mr Hu, 37, served a three-and-a-half-year prison sentence for "inciting subversion". His term had been set to end on Sunday.
There is a heavy police presence outside Mr Hu's Beijing home and he now appears to be under some form of house arrest, a BBC correspondent says.
Mr Hu's release coincidentally follows that of artist Ai Weiwei last week.
Mr Ai's detention in April had prompted a global campaign for his release. The Chinese authorities say Mr Ai, 53, has confessed to tax evasion offences.
Mr Hu's wife, Zeng Jingyan, said in her Twitter post that her husband had been freed at 0230 local time on Sunday (1830GMT on Saturday).
