Trustees have been appointed for Zaman newspaper, a daily linked to US-based cleric Fethullah Gulen, a Turkish court said on Friday.
In a related story, four Turkish businessmen were detained as part of an investigation into the “parallel state” earlier on Friday, local police said.
Boydak Holding Executive Board Chairman Haci Boydak and his younger brother, CEO Memduh Boydak, are accused of being members of and providing financial support to the “parallel state," while two other executives – Murat Boydak and Erol Boydak – are accused of spreading propaganda for the organisation on social media.
Known also by the initials FETO/PDY, the parallel state designates a clandestine group of Turkish bureaucrats and senior officials, allegedly embedded in the country’s institutions, including the judiciary and the police.
Previously, police raids also targeted Gulen-affiliated conglomerates; including, Koza Ipek Holding and Kaynak Holding, both high profile Turkish companies.
Since early 2014, investigations into the parallel state have seen hundreds of suspects, including police and public prosecutors, arrested or reassigned.
An arrest warrant has been issued for Fethullah Gulen, in absentia, for "attempting to stage a coup, establishing and masterminding an armed organisation and political espionage” in Turkey.
An upcoming hearing will be held in April 2016.
