Thirty-five people in Izmir province were detained as part of an investigation into the Gulen movement, which the government accuses of leading the July 15, 2016 coup attempt, on Monday.

State-run Anadolu news agency reported that police carried out simultenaous operations in Izmir’s Kemalpasa, Tire and Odemis districts and rounded up 35 people including teachers,

The suspects are accused of having used ByLock mobile application, which Turkish authorities believe is a communication tool among Gülenists.

Tens of thousands of people, including civil servants, police officers, soldiers, businessmen and homemakers, have either been dismissed or arrested for using ByLock or having accounts at the now-closed Bank Asya since the failed coup attempt last year.
