Photojournalist Çağdaş Erdoğan was arrested after spending 12 days under custody, on Sept 13.

Detained while taking photos in Istanbul’s Kadikoy district on Sept 2, Erdoğan was put in pretrial arrest on accusations of membership to a terrorist organization on Wednesday.

Erdoğan is alleged to have taken pictures of a building that belongs to the National Intelligence Agency (MIT).

The globally acknowledged journalist was ranked among “Ones to Watch” list by the British Journal of Photography early this year. Erdoğan’s works have appeared in several foreign media outlets including New York times, Guardian, Wall Street Journal, Washington Post, Newsweek, Politico, Bloomberg, BBC and Buzzfeed.

Turkey has arrested at least 301 journalists since the last year’s abortive coup, of whom more than 170 still remain behind bars.
