Lt. Col. Levent Turkkan, the former aide-de-camp of the Chief of General Staff Hulusi Akar said his testimony was taken under torture, during his first court hearing on Tuesday.

“None of my statements are genuine. I was all destroyed. They drip-fed me. They x-rayed my brain. I didn’t have genuine statement,” Turkkan said.

Turkkan’s alleged confession is considered to be among main evidence backing up government narrative that the Gulen movement masterminded the July 15, 2016 coup attempt.

Detained on July 16, Turkkan reportedly confessed to prosecutor in his initial testimony that he had wiretapped Turkey’s top general Akar for years on behalf of the movement and that he led the group who held Akar hostage during the coup night.

Rejecting his earlier statements, Turkkan underlined that his testimony was taken under.

Turkkan was pictured with his rib cage and hands in bandages in a state-run Anadolu Agency picture, released along with his testimony.

Human rights groups Amnesty International and Human Rights Watch earlier stated that they had received credible evidence of detainees in Turkey being subjected to beatings and torture, including rape, since the failed coup on July 15.
