Financial Crimes Units are investigating the premises of a business and media group, Koza Ipek, in Ankara known to be affliated with the US-based Fethullah Gulen who has been accused of trying to overthrow the Turkish government.
Anadolu Agency reported on Tuesday that 23 companies in Ankara linked to Koza Ipek Holding were raided over suspicions of providing financial support to the movement led by Fethullah Gulen and of conducting propaganda for the group.
The Turkish government accuses the movement of organising a corruption scandal in 2013 to destabilise it and has called the movement a threat to Turkey's national security.
Computers and documents belonging to the company have been reportedly confiscated by the police, which have stated that company CEO Akın İpek is abroad.
Koza Ipek Holding owns opposition television stations Bugun TV and Kanal Turk, which were also subject to an operation led by Turkey’s Financial Crime Investigation Board (MASAK), as well as the Bugun and Millet newspapers, among other business interests.
The Koza Ipek Corporation is active in the media, energy and mining sectors and the company is accused of financial fraud, tax evasion and graft.
Akın Ipek said earlier in a written statement that "Our group cannot be part of a crime scenario even if it is fictional," and vowed to "disprove the slander with documents."
Shares in the corporation's energy and gold mining companies dropped more than 10 percent on the Istanbul Stock Exchange following the police operation.
The financial accounts of the company are being investigated by police, with Turkish government officials saying that they are determined to lawfully stand against the Gulen Movement, whose followers have been accused of infiltrating state institutions to gain control of state mechanisms, illegal wiretapping, forgery of official documents and spying.
