At least 13 people were detained as part of an investigation into the Gulen movement followers in Kahramanmaras, on Tuesday.

Detention warrants were earlier issued for 13 teachers who were earlier dismissed from their jobs over alleged links to the movement. Kahramanmaras police detained 9 of the suspects by Tueday afternoon.

The detainees also included 4 former employees of the now-defunct Bank Asya.

The prosecutor overseeing the investigation accuses the suspects of having used ByLock, a mobile application claimed to be the once-top communication tool among Gulen sympathizers.

Turkey survived a military coup attempt on July 15 that killed over 240 people and wounded more than a thousand others.

Immediately after the putsch, the AK Party government along with President Recep Tayyip Erdoğan pinned the blame on the Gülen movement. The movement denies any involvement.
