Investigation into the death of singer Giorgos Mazonakis at a private clinic

The death of popular Greek singer Giorgos Mazonakis, who suffered a fatal cardiac arrest on September 9, 2026, during a plasmapheresis treatment at a private clinic in the Kolonaki district of Athens, has triggered a major criminal investigation. Authorities have arrested two doctors, Ioanna Gaka and Ilias Theodoropoulos, who now face felony charges of fatal exposure to danger. Evidence suggests that the medical team attempted to obstruct the investigation by deleting records and tampering with digital equipment at the clinic. Testimony from a taxi driver contradicts the doctors' original claims regarding the singer's arrival time, indicating he was present at the facility for several hours longer than stated. Additionally, the Athens Medical Association has clarified that plasmapheresis is strictly prohibited in private clinics and confirmed that the facility was operating without proper authorization for such procedures.

Further revelations have emerged regarding the clinic's practices, with former patients alleging that Dr. Theodoropoulos promoted pseudoscientific treatments, including excessive vitamin intake and bowel cleansing, for severe conditions like cancer, while claiming divine status. Police are currently analyzing retrieved digital data to establish a precise timeline of the emergency response. The two defendants are being held in custody and are scheduled to testify on Monday, September 14, which is also the date set for the singer's funeral at the Third Cemetery of Nikaia.
