Detention warrants were issued for 112 people as part of an investigation into the now-defunct Journalists and Writers’ Foundation (GYV), on Wednesday.
An Istanbul prosecutor ordered warrants against GYV’s former members and executives in 16 provinces, media said.
35 of the suspects were rounded up at the time of this writing while police were seeking the remaining 77.
GYV was earlier closed-down as part of its links to the Gulen movement, which the government accuses of masterminding the July 15, 2016 coup attempt.
The movement denies involvement in the failed putsch.
