Detention warrants were issued for a total of 93 people as part of an investigation into the Gulen movement in Ankara, on Thursday.
The suspects consist of teachers and other staff who used to work at FEM Dersanesi, a prep schoold that the government earlier closed over its links to the Gulen movement.
Police carried out operations in several provinces to detain the suspects upon the warrants issued by an Ankara prosecutor.
Turkish government accuses the movement of being behind the failed coup of 2016 while the latter denies involvement.
48 of the suspects were reportedly located in Ankara, 41 in other provinces and the remaining 4 abroad.
