A total of 30 civilians, including businessmen and housewives, 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 pro-gov’t Yeni Şafak daily, the operations, which were based in the eastern province of Batman, were conducted across 21 provinces, including Trabzon, Antalya, Konya, Diyarbakır 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.
