Umut Güner, owner of Dünya newspaper, has reportedly been detained in the Istanbul chief prosecutor’s investment-fund investigation. Sözcü and Cumhuriyet also carried the news.

Reports allege a connection to the ownership relationship between Dünya Holding and Bulls Yatırım Holding. Citing KAP records, Cumhuriyet put Bulls’ stake in Dünya Holding at 20.45%.

No detailed account of police procedures or specific allegations against Güner has been reported. Detention is distinct from remand and from a final conviction.
