The Turkish Interior Ministry announced on Monday that 209 people were detained last week as part of investigations into the faith-based Gülen movement.
Police took more than 15,000 people into custody over alleged Gülen links in the first half of the year.
Turkey survived a coup attempt on July 15, 2016 that the government accuses the movement of orchestrating, an allegation strongly denied by the movement.
Since then more than 200,000 people were investigated for alleged affiliation with the movement, according to Justice Ministry.
Also on Monday, Bursa Chief Prosecutor’s Office issued detention warrants for 25 former police officers who were dismissed from their jobs by a government decree. 21 of them were detained by local police.
