Mazonakis Investigation Uncovers Contradictions Between Arrested Doctors 

New contradictions and inaccuracies have emerged in the investigation into the death of Greek singer George Mazonakis, providing key clues into how authorities reached the decision to arrest the two doctors. The couple, who ran a private clinic in Kolonaki, are due to appear before a prosecutor on Friday morning, 11 September (Athens time), facing charges of fatal exposure.

According to information from the investigation, the female doctor’s statement contains several inconsistencies. She initially said that she had only inserted the “butterfly” needle into Mazonakis. However, paramedics reportedly told investigators during the preliminary inquiry that the plasmapheresis machine was operating normally when they arrived at the clinic.

Investigators have also found that the plasmapheresis machine remained active for 45 minutes the last time it operated. Authorities are expected to conduct a further, more detailed examination to establish precisely how long the machine was running.

Another factor that led to the doctors’ arrests was the apparent lack of the necessary licences for the two plasmapheresis machines kept at the clinic.

A post-mortem examination is expected to shed further light on the circumstances surrounding Mazonakis’ death. Authorities had scheduled the procedure for Thursday but postponed it until Friday after the singer’s family appointed a technical adviser to monitor the examination.

Police conduct extensive search of Kolonaki clinic

Earlier, authorities brought the two doctors to the Athens Security Directorate following a lengthy search of their clinic on Karneadou Street in Kolonaki.

Police officers from the Athens Security Subdivision conducted an extensive search of the premises. Shortly before 4pm, officers removed four large bags marked “evidence” from the clinic.

About an hour later, police left the clinic with the two doctors and continued their investigation at the couple’s home in Psychiko.

During the inspection, which also involved a team from the Athens Medical Association (ISA), authorities found two plasmapheresis machines for which no relevant authorisation existed.

The ISA said inspections carried out at the clinic in 2024 and 2025 had not recorded the two machines.

The association also clarified that the premises held a licence to operate as a pathology clinic, where the installation and use of such equipment is not permitted.

The ISA stressed that plasmapheresis is a complex medical procedure that should take place only when there is a clear medical indication and with appropriately trained personnel. It also said such procedures should never take place in a clinic that lacks the facilities needed to manage potential complications.

Authorities seized mainly digital evidence from the clinic, including electronic devices and files, as well as medical preparations found on the premises.

Investigation extends to doctors’ home

The investigation later extended to the doctors’ home in Psychiko.

Shortly before 6pm, Greek Police officers searched the property for around 10 minutes. The couple then went to the Athens Security Subdivision in Kypseli.

There, investigators are expected to take further statements from both doctors in light of the new findings.

Authorities have now gathered the preliminary investigation material from the search of the couple’s home and the examination of the medical equipment at the Kolonaki clinic.

The post-mortem examination and further forensic findings are expected to provide crucial evidence about the circumstances and cause of Mazonakis’ death.
