Warrants were issued for 59 people as part of an investigation into the Gulen movement, state-run Anadolu news agency reported on May 30.
The Ankara-based investigation implicated 59 people who are accused of having deposited donations collected on behalf of the movement into Bank Asya accounts.
29 out of 59 were detained as a result of initial police operations, Anadolu said.
Turkish government blames Gulenists for the July 15, 2016 failed coup while the group denies involvement.
Having Bank Asya account is considered a sign of links to the movement.
