Selahaddin was returned to Turkey by agents of the National Intelligence Organization, Turkish media reported.
Turkish agents have captured a nephew of US-based Muslim leader Fethullah Gulen in a foreign operation and taken him to Turkey where he is being prosecuted.
Selahaddin Gulen, wanted in Turkey on charges of belonging to a terrorist organization, was confiscated in an operation by Turkish national spy agency MIT, Turkish state news agency Anadolu reported on Monday.
The report did not indicate where he was captured or when he was returned to Turkey. Selahaddin was believed to reside in Kenya.
On May 6, a Kenyan court banned the arrest and extradition of Selahaddin to Turkey, according to legal documents seen by the AFP news agency.
The court also ordered the return of his passport and said he should be allowed to return to the United States.
Selahaddin, for whom a red Interpol warning was issued at the request of Turkey, arrived in Nairobi on October 17, 2020 and was arrested before being released on bail two days later. His lawyer was not available for comment.
His case is the latest in a series of forced repatriations of people affiliated with the Gulen movement, which the Turkish government blames for a failed coup attempt in 2016.
Gulen, a former ally of Turkish President Recep Tayyip Erdogan, who now lives in the US, has denied the allegations.
Turkey has designated its network as a terrorist group, which it has dubbed the Fetulaist Terrorist Organization or FETO.
In early May, Erdogan announced that a prominent member of Gulen’s network had been captured but did not provide details.
