A total of seven people were detained as part of an Usak-based investigation into the suspected followers of the Gulen movement on Wednesday.

The public prosecutor’s office in Turkey’s western province of Usak issued detention warrants for 5 military officers, 1 academic from Usak University and 1 businessman who owns a local newspaper in the city. Among the detained military officers are 2 helicopter pilots.

Police raided premises of the suspects and detained them on accusation of being involved in the movement’s alleged, “encrypted” network within the army.

Turkish government blames the Gulen movement for the failed coup attempt on July 15, 2016 while the latter denies involvement.

More than 160,000 people have passed through police custody, of which 90,000 were remanded in prison pending trial over Gulen links since the summer of 2016.
