Turkey’s National Intelligence Organisation (MIT) arrested a man over links to the Gülen movement, which Turkey accuses of orchestrating a coup attempt in 2016, and brought him back to Turkey, the state-run Anadolu Agency reported on Saturday citing security sources.

Reuters reported on Friday that Osman Karaca, a Turkish-Mexican national, was arrested on Oct. 14 in Cambodia’s capital Phnom Penh.

Karaca was arrested on charges of “founding and masterminding an armed terrorist organisation,” an unnamed source told Anadolu.

Karaca, who was born in Turkey and holds a Mexican passport, was the director of Zaman International School from 2002 to 2011, his wife told Reuters. The school was sold last year.

More than 77,000 people have been jailed pending trial, and about 150,000 civil servants, military personnel and others have been sacked or suspended from their jobs in Turkey over alleged links to Gülen since the failed putsch in 2016.

The government is also taking action against Gülen’s schools that had operated in 160 countries before the crackdown, by putting pressure on foreign governments to close these establishments.
