Fifteen people from a private security company in Eskisehir were detained over their alleged use of ByLock, a controversial mobile application that Turkihs authorities claim to be the top communication tool among Gulen movement members, on Wednesday.

Turkish government accuses the movement of masterminding the July 15, 2016 coup attempt while the latter denies any involvement.

More than 120,000 people have been detained and some 50,000 including academics, judges, doctors, teachers, lawyers, students, policemen and many from different backgrounds have been put in pre-trial detention since July 15, 2016.
