Kolonaki clinic investigation follows death of singer Giorgos Mazonakis FAST-MOVING

Giorgos Mazonakis apheresis machine medical negligence Kolonaki clinic Greek singer death

Investigations are intensifying into the death of Greek singer Giorgos Mazonakis, who collapsed during an apheresis procedure at a private clinic in Kolonaki. Doctors Ioanna Gaka and Ilias Theodoropoulos face felony charges of causing death by exposure, a charge that carries a potential sentence of 5 to 10 years.

Authorities have identified significant contradictions in the doctors' testimonies. While the clinic claimed Mazonakis arrived at 16:00, security footage shows him entering around 14:00. Furthermore, evidence suggests the apheresis machine had been operating for approximately 42 minutes before the collapse, contradicting claims that the procedure had not yet begun.

Police have also reported attempts to digitally delete evidence, including the singer's appointment records and a photograph of him on the medical bed, though some data has been recovered. The investigation is also scrutinizing a critical 87-minute delay between the incident and the call to emergency services (EKAB).

The Medical Association of Athens has raised concerns regarding the clinic's oversight, noting that apheresis machines were not detected during previous inspections in 2024 and 2025. Additionally, the Greek Hematology Society has previously warned about the risks of unregulated alternative therapies and 'longevity' services.
