At least 34 people have been detained over their alleged use of ByLock mobile application, which the government believes to be a top communication tool among Gülen movement followers.

The detainees are reported to be health personnel who were earlier dismissed from their positions as part of administrative investigations into the movement which is accused by the government of having organized a coup attempt on July 15, 2016.

Police in 15 provinces carried out operations to round up 34 suspects in a Konya-based probe. Detention warrants were still outstanding for another 31 health personnel, according to Anadolu news agency.

Critics often blast the government for detaining thousands simply for using a mobile application.
