Investigation launched following the death of singer Giorgos Mazonakis

Popular Greek singer Giorgos Mazonakis passed away on September 9, 2026, at the age of 54, after suffering a cardiac arrest during a plasmapheresis procedure at a private clinic in Kolonaki, Athens. Authorities are currently investigating whether the facility was licensed to perform such medical procedures, with the Minister of Health, Adonis Georgiadis, describing the location as a "supposed clinic." The facility was searched by the Greek police's special division, leading to the seizure of evidence.

Two doctors associated with the clinic have provided initial statements to the authorities and remain under investigation. The attending physician claimed she informed Mazonakis that the treatment carried no significant side effects, noting he visited the clinic in poor health on September 8 to prepare for an upcoming concert scheduled for September 20. Medical experts have highlighted the inherent risks of performing plasmapheresis outside of hospital environments.

A scheduled autopsy was postponed until September 11, 2026, following a request by the artist's family to appoint a private technical advisor to participate in the proceedings. The investigation into the clinic's operations and the specific circumstances of the singer's final hours continues.
