A total of 19 police officers were detained as part of ongoing operations throughout Wednesday targeting the alleged followers of the Gülen movement due to their use of a smart phone application known as ByLock.

According to Evrensel daily, the operations, which were based in the eastern province of Sivas, were conducted across 13 provinces, including İstanbul, Ankara, Mersin, Antalya and İzmir.

Turkish authorities believe ByLock is a communication tool between members of the 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 detained police officers were already dismissed from profession with recent decrees issued by Turkish government in the aftermath of the coup attempt.
