Detention warrants were issued for a total of 70 teachers as part of an investigation into the Gulen movement, on Friday.
Police carried out operations to detain 70 teachers upon the warrants issued by an Ankara prosecutor.
The suspected teachers used to work for the schools which were closed down by the government over Gulen links.
Turkish government accuses the movement of being behind the failed coup of 2016 while the latter denies involvement.
At least 25 teachers in the Black Sea province of Samsun were detained over similar charges the other day.
