ISTANBUL, March 18 Shares in Dogan Yayin DYHOL.IS and other Dogan Holding (DOHOL.IS) companies, including fuel retailer Petrol Ofisi PTOFS.IS, have been suspended, Istanbul's stock exchange said on Wednesday.
The exchange is seeking more information from Dogan over an ongoing tax row, according to a filing.
Dogan Yayin, Turkey's largest media group, said on Tuesday the tax office had rejected the company's Kanal D and Star TV brands as collateral for an approximate $500 million tax fine.
Petrol Ofisi is a joint venture between Austria's OMV OMV.VI and Dogan Holding.
