Ece Sevim Öztürk, a Turkish investigative journalist who produced a documentary on a controversial coup attempt on July 15, 2016 and promised to shock Turkey with her forthcoming book on the subject, was detained on Friday on charges of “disseminating terrorist propaganda,” according to a report by Çağdaş Ses, the left-wing online news outlet she worked for.

Öztürk had been a popular guest even on pro-government news programmes in recent months after choosing to focus on speaking to eyewitnesses and piecing together the events that led up to the attempt.

But in recent days, pro-government Islamist newspaper Yeni Şafak and neo-nationalist online news outlet OdaTV began to attack her as a sympathiser of the Gülen movement, and she was detained early Friday morning.

It is common in Turkey for journalists to be investigated and jailed for their work. Turkey is ranked 157th among 180 countries in the 2018 World Press Freedom Index released by Reporters Without Borders (RSF). If Turkey falls two more places, it will make it to the list of countries on the blacklist, which have the poorest record in press freedom.
