Istanbul police raided the house of Can Dündar, the former editor-in-chief of daily Cumhuriyet, on Sunday.
The raid came as 14 arrest warrants were issued for Cumhuriyet journalists and executives on charges that the suspects were “committing crimes on behalf of the Fethullahist Terror Organization (FETÖ) and the PKK even if the newspaper was not a member in them.”
A similar notice was previously issued for Dündar in a case related to the alleged transfer of weapons by Turkey’s intelligence services to rebels in Syria.
An Istanbul court had accepted an indictment against Dündar on charges of “printing and publishing terrorist organizations’ statements” during his one-day editorial duty undertaken in solidarity with a now-closed daily Özgür Gündem newspaper.
He was earlier this year sentenced to five years and 10 months in prison for revealing state secrets in a report on a shipment of arms intercepted at the Syrian border in January 2014.
Dündar is believed to be outside the country after he was freed earlier this year pending an appeal against the conviction.
He said last month that he would not surrender himself to the Turkish courts because he had lost faith in the judiciary after the failed July 15 coup and the subsequent state of emergency declared by the government.
