At least 12 people including housewives, teachers, university personnel and some police officers were taken into custody for interrogation as part of an investigation into the Gulen movement, on May 18.

Igdir based operation accuses the suspects of membership the movement, which the government pinned the blame on for the July 15, 2016 coup attempt.

State-run Anadolu news agency said two of the detainees were later released.
