88 suspects allegedly affiliated with the Gülen Movement have been detained in operations carried out in nine cities including Istanbul throughout Turkey over unlawful financial support.
According to reports, the operations were carried out under the scope of an investigation regarding the funds collected by the Gülen Movement between 2004 and 2015 under the name of donations.
Gülen-Movement affiliated Bank Asya employees are amongst the detaines, reports have said.
A total of 140 detention warrants have been issued and more detentions are expected.
The financial arm of the Gülenist Terror Organization (FETÖ), an affiliate of the Gülen Movement named in indictments in Turkey, is accused of a string of wrongdoings, including two coup attempts.
The suspects face accusations of financing FETÖ through charity donations - called "himmet" by the movement's followers - which they collected from unsuspecting followers of Gülen, or through extortion of businesspeople.
The Gülen Movement, which over the past three years has seen members and sympathizers purged from state institutions including the police and judiciary, was designated by authorities as a national threat, a classification used for terrorist organizations, following two coup attempts by movement followers and accomplices.
