İsmail Türk, the editor-in-chief of the online news portal Haber Erk and a former columnist for the Yenicag daily newspaper has been taken into custody over his alleged ties to the Gulen movement.
Ankara police caught Turk at Esenboga airport as part of an investigation into the movement, which the government accuses of masterminding the July 15, 2016 coup attempt, on Nov 29.
The group denies involvement in the failed attempt.
Pro-government Sabah newspaper said Turk would write columns for the movement-linked Rota Haber and often appear at Samanyolu TV as commentator before both media outlets were shut down over Gulen links.
Sabah also accused Turk of supporting Meral Aksener againt Devlet Bahceli, the nationalist party leader who has dramatically turned from opposition to an ally of the President Recep Tayyip Erdogan.
At least 308 journalists have been put in pretrial detention after police custody since July 15, 2016. Even though some were later released pending trial, nearly 180 are still held behind bars.
