Detention warrants were issued for 36 people in 16 provinces as part of an Aksaray-based investigation into the Gulen movement, on Tuesday.
State-run Anadolu news agency said
Anadolu said most suspects are sought for their employment at Gulen-affiliated companies.
20 of them have been detained at the time of this writing.
Turkish government accuses the movement of masterminding the July 15, 2016 coup attempt while the latter denies involvement.
Nearly 150,000 people have been detained and 60,000 arrested over ties to the movement since the summer of 2016.
