Police have raided a private high school in Bursa, and detained the owner, his wife as well as the school’s principal as part of an investigation into the Gulen movement.

State-run Anadolu news agency reported Thursday that detention warrants were issued for the three and their homes as well as the Mavi Deniz Anatolian High in Bursa’s Odunluk neighborhood which remained closed over Gulen links for some time earlier was raided.

The owner, identified as I.D., his wife M.D., and the principal S.K. were taken into police custody.

Police seized some documents and the hard drives of the computers at the school.

Anadolu said the school is accused of receiving funds from some other schools that were closed down for good over Gulen links. Teachers and students at such schools were also transferred to Mavi Deniz school, Anadolu noted citing the investigation.

Turkish government accuses the Gülen movement of masterminding a failed putsch on July 15, 2016, and considers it a terrorist organization. The movement denies involvement in the coup and terror accusations.

The total number of schools, dormitories and universities that saw closure over Gulen links since the failed coup totals around 3,010.
