A total of 65 civilians, including businessmen and housewives, were detained as part of ongoing operations throughout Saturday targeting the alleged followers of the Gülen movement due to their use of a smart phone application known as ByLock.

According to pro-gov’t Sabah daily, the operations, which were based in the western province of İzmir, were conducted across 28provinces, including Ankara, Manisa, Konya, and İstanbul.

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.
