Eighteen out of 25 former police officers who were recently detained as part of an Erzincan-based operation across 11 provinces have been arrested due to their use of a smart phone application known as ByLock.
Seven of the police officers were released on judicial probation.
Turkish authorities believe ByLock is a communication tool between members of the faith-based Gülen movement.
Tens of thousands of civil servants, police officers and businessmen have either been dismissed or arrested for using ByLock since a failed coup attempt last July.
The police officers had already been dismissed by means of recent decrees issued by the Turkish government in the aftermath of the coup attempt.
