Enver Altaylı, (76), a former member of the Turkish Intelligence agency (MIT), has been kept in solitary confinement since early 2018 over alleged links to the Gulen group, which the government accuses of masterminding a coup attempt in 2016.

The group denies any involvement.

According to the Kronos news portal, Altaylı on Thursday denied the accusations at the last hearing of his trial at the Ankara 16th High Criminal Court. He also requested his release from the solitary confinement, which, he said, turned out to be a “pure torture.”

Altaylı is a well-known figure in the country’s recent history who worked closely with former presidents Süleyman Demirel and Turgut Özal. He was arrested on August 27, 2017, one year after the failed coup. He also filed many complaints claiming that he faced torture in police custody and that in prison he were being held in appalling conditions bordering on torture.
