Daily Hürriyet reporter Arda Akın has joined the list of journalists arrested as part of the nationwide probe following Turkey’s failed military coup attempt of July 15.

An İstanbul court ordered Akın’s arrest late on Aug. 15. Akın had initially been released on probation in the investigation, which witnessed the arrest of 18 journalists.

However, the Public Prosecutor’s Office appealed the release of Akın and a second detention warrant was issued for him. Akın was then detained on Aug. 15 at a police station and the Istanbul Criminal Court of Peace later ordered his arrest pending trial.

Akın is known for columns that deeply disturbed the Turkish government.
