Ninety-one civilians were arrested by a Turkish court on Saturday due to alleged use of a smart phone application called ByLock and links to the Gülen movement, which the Turkish government blames for a failed coup last July, the state-run Anadolu news agency reported.

According to the report, police detained a total of 235 people on Jan. 21 in simultaneous raids across Turkey. Of those, 91 were sent to jail late on Saturday.

Arrestees are reportedly accused of using ByLock and having secret links to the Gulen Movement.
