Turkish authorities have issued an arrest warrant for journalist Can Dündar as part of an investigation into the 2013 Gezi Park protests in Istanbul, state-run Anadolu Agency said on Dec. 5.

Prosecutors said Dündar played an active role in the protests and provoked public unrest through social media.

It is not clear how the warrant can be served because Dündar, former editor-in-chief of the Cumhuriyet newspaper, fled to Germany after being convicted in 2016 on charges of “leaking state secrets.”
