Nine teachers were detained in Turkey’s Malatya province as part of an investigation into the followers of the Gülen movement, on Friday.
The teachers are accused of using ByLock mobile application, which the prosecutors claim a primary communication tool among sympathizers of the movement.
Detention warrants were issued for 10 teachers who were earlier dismissed from their jobs over ties to the movement. Nine of the accused have been taken under custody so far.
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 government along with President Recep Tayyip Erdoğan pinned the blame on the Gülen movement which denies involvement.
About 120,000 people have been sacked from state bodies, in excess of 80,000 detained and more than 40,000 have been arrested since the coup attempt. Arrestees include journalists, judges, prosecutors, police and military officers, academics and governors.
