One of the suspects, Emin Özcan, said they were subjected to a test around 15 days before the foiled coup and that the results were announced on July 15, 2016. According to Özcan’s testimony, those who succeeded on the tests left the barracks while those that failed were not allowed to leave.

“If I had been successful in that test, I would have left the barracks. The reason I’m here today is the fact that I failed that test,” he said.
