China human rights lawyer Ge Yongxi detained
Mr Ge was taken from his Guangzhou home overnight, with no explanation from the authorities, the lawyer told the BBC.
Some reports suggest Mr Ge`s detention may be linked to social media posts he made mocking China`s censorship of news about the leaked Panama Papers.
Those papers showed that relatives of several Chinese leaders had links to offshore firms.
It is understood that Mr Ge has been accused of "publicly humiliating others", the BBC`s Shanghai correspondent Robin Brant reports.
The civil rights campaigner was last detained 10 months ago, then released after a public petition, our correspondent adds.
