# Turkish football corruption probe triggers TFF resignations > Live situation record from CLSTR: https://clstr.news/situations/turkish-football-referee-corruption-investigation > Updated: 2026-10-01T20:16:37.000Z. Sources: 142. Developments: 4. The investigation into corruption and sports crimes within Turkish football has escalated, causing significant instability within the Turkish Football Federation (TFF). Following a massive betting probe, the TFF Legal Counsel referred 448 officials from the Süper Lig and TFF 1. Lig, who served over the last five years, to the Professional Football Disciplinary Board (PFDK) on betting-related grounds. This action has triggered a wave of high-level resignations, including TFF Board Member Ural Aküzüm, several reserve members, and the heads of the Foreign Relations and Amateur Affairs boards. While legal experts note that TFF statutes do not mandate an automatic dissolution of the board due to these departures, the internal structure remains in flux. Tensions have also risen between the TFF and the Istanbul Chief Public Prosecutor’s Office. The Prosecutor’s Office reportedly issued a written warning to the TFF to coordinate disciplinary actions with the ongoing judicial investigation to prevent the flight of suspects or the destruction of evidence. However, the TFF proceeded with its referrals without such coordination. As the probe continues, Süper Lig referee Yasin Kol and assistant referee Göktuğ Hazar Erel remain in custody as part of the broader investigation into allegations including forgery and abuse of duty. ## Claims - The Istanbul Chief Public Prosecutor's Office is conducting an investigation into the Central Referee Board (MHK) regarding illegal betting and sports crimes.
