Detention warrants have been issued for 79 Ankara teachers as part of an investigation into Turkey’s Gülen group, which is accused by Turkish authorities of orchestrating a failed coup in Turkey last year.

According to the Hürriyet daily, the suspects are used to work for now-closed Gülen affiliated private and prep-schools in several different provinces

Among the individuals for whom detention warrants have been issued as part of an Ankara-based operation are those accused for using a smart phone application known as ByLock.

Turkish authorities believe ByLock is a communication tool between members of the Gülen group.

Turkey experienced a military coup attempt on July 15 that killed over 240 people and wounded more than a thousand others. Immediately after the putsch, the Justice and Development Party (AK Party) government along with President Recep Tayyip Erdoğan pinned the blame on the Gülen group.

More than 145,000 people have lost their jobs while over 120,000 were detained and some 55,000 were put in pre-trial arrest over ties to the movement since last summer.
