Prominent Kenyan human rights activist Boniface Mwangi has been released without charge after being detained by police on suspicion of inciting violence, his wife told the BBC.
She described on Sunday how six masked individuals forcibly took him from his home.
His detention came after he called for an anti-government protest at a marathon in the capital, Nairobi, on Sunday.
The police had confirmed that Mr Mwangi was in custody but did not provide further details.
His detention caused outrage among his supporters, who demanded his release.
