Nusret Altinbas surrenders to Turkish authorities over capital markets scandal

On October 25, 2026, Nusret Altinbas, the owner of Altinbas Holding, surrendered to Turkish authorities following the issuance of an arrest warrant. He is a primary figure in a major investigation into illegal transactions within the Turkish capital markets. His brother, Inan Altinbas, was also taken into custody earlier in relation to the same case.

The investigation has resulted in the arrest of 15 additional individuals and the freezing of assets belonging to the involved families. Notable figures among the detainees include Taha Cakmak, the former general manager of Turkiye Sigorta and Turkiye Hayat Emeklilik, as well as Ertan Aydin, a former advisor to the Turkish President, who also faced an arrest warrant and was brought before the justice system.

The probe focuses on widespread financial irregularities, though official sources have not yet provided a specific timeline for upcoming court dates or the next procedural steps in the judicial investigation. The situation remains under active scrutiny as authorities continue to process those detained.
