At least 538 people were detained as part of investigations into the Gülen movement over the past week, according to government data.
In a written statement on Monday, the Interior Ministry said 568 people were rounded up in operations targeting the Gülen movement between Nov 26 and Dec 3.
Turkish government accuses the movement of masterminding the July 15, 2016 coup attempt while the latter denies involvement.
Over 220,000 people have been detained and 90,000 arrested over ties to the movement since the summer of 2016.
The ministry’s statement also said 10 others were detained over ties to what the government says radical leftist organizations in the past week.
