Detention of Murat Sabuncu comes after closure of several opposition media organisations since July’s failed coup bid.
Turkish police have detained the editor-in-chief of Cumhuriyet, an opposition newspaper, according to Turkish media reports.
Reports say that along with Murat Sabuncu, Guray Oz, a Cumhuriyet columnist, was also detained on Monday morning.
Their residences were being searched, the reports said.
Cumhuriyet, known for its critical stance towards the government, had got wide international attention in 2015 when it reported on a group of Syria-bound trucks allegedly sent by the country’s intelligence agency, carrying weapons to Syrian anti-government fighters.
The reports did not give a reason for the detentions or the searches, which came as authorities crack down on anyone suspected of links to Fethullah Gulen, the US-based religious leader accused by the Turkish government of orchestrating a failed coup in July.
Scores of opposition media organisations have been shut down since the government acquired state of emergency powers following the failed coup.
