Turkish security services have detained a nephew of exiled cleric Fetullah Gulen overseas and brought him back to Turkey, local media have announced.
Selahaddin Gulen has been accused of belonging to an outlawed organisation headed by his uncle.
The announcement did not say where he was detained.
But his wife Serriye, a teacher in Kenya, said in a video on social media that her husband had gone missing in Nairobi in early May.
Turkey's Anadolu news agency published a photograph of Mr Gulen in handcuffs, with Turkish flags on each side of him.
The outlet did not say if his capture - carried out by Turkey's National Intelligence Organisation (MIT) - had been made in agreement with Kenya.
His uncle Fetullah Gulen has been accused of masterminding a failed military coup in 2016 which killed 251 people and injured more than 2,000.
