Ümit Kozan - Hasan Yıldırım / Ankara, Sep 1 () - Turkish police have raided companies in Ankara belonging to Koza İpek.

The raid, launched at around 8 a.m., was first reported by Kanaltürk and Bugün television stations, two media outlets owned by the corporation, which were also subjected to an operation led by Turkey’s Financial Crime Investigation Board (MASAK).

A police search has also been launched at İpek University, as well as Akın İpek’s house in Ankara. The Koza İpek Corporation is active in the media, energy and mining sectors.

Akın İpek said in a written statement on Aug. 31 that the corporation's 27 companies had been under financial inspection for the past two years. "Our group cannot be part of a crime scenario even if it is fictional," he said, vowing to "disprove the slander with documents."

Stocks of the corporation's energy and gold mining companies dove more than 10 percent on the Istanbul Stock Exchange in the immediate aftermath of the police operation.
