Greek police investigating the fatal collapse of singer Giorgos Mazonakis at a private clinic in Kolonaki have reopened evidence from a previous anabolic steroid trafficking ring after discovering prescriptions linked to one of the clinic's doctors.
The development follows the arrest of two physicians associated with the medical practice on Karneadou Street, where the 54-year-old artist suffered a fatal cardiac arrest on Wednesday, September 8.
Mazonakis was a prominent Greek Laiko and pop singer whose career spanned several decades. Kolonaki is an upscale district in central Athens known for luxury boutiques and private medical offices.
According to a report by Greek television channel Star, investigators are re-evaluating findings from an earlier probe into an illegal steroid manufacturing and distribution network. During that prior investigation, officers raided a pharmacy suspected of operating as a preparation lab for anabolic substances.
Inside the pharmacy, investigators discovered prescriptions bearing the name of Dr. Ioanna Gaka. Gaka is married to Dr. Ilias Theodoropoulos, who operated the private practice in Kolonaki where Mazonakis suffered his fatal emergency.
Authorities are examining whether the older records hold any relevance to the current fatality probe. Police emphasized that no evidence has been established connecting the previous steroid case to the singer's death.
Police search singer home in Voula
On Thursday evening, September 10, officers from the Greek Police Security division extended their investigation to Mazonakis's residence in Voula, a coastal suburb south of Athens. The search took place hours after prosecutors issued oral arrest warrants for the two doctors.
Officers arrived at the property shortly after 6:00 p.m. carrying a court order. Because the residence was locked, police required the assistance of a locksmith to gain access before searching the interior rooms and the garage for evidence.
One of the singer's sisters was inside the residence when officers arrived. She spoke briefly with police before leaving the premises. The singer's family has formally declared its participation in support of the prosecution against any responsible parties.
The two arrested doctors face charges of fatal exposure, an offense under Greek law involving a breach of care resulting in death. They are scheduled to appear on Friday before prosecutors at the former Evelpidon School court complex in Athens.
Security cameras show missing hours
Investigators are focusing on significant discrepancies regarding the exact time Mazonakis entered the medical office on Karneadou Street.
According to investigative information, one of the arrested doctors testified that the singer arrived at the clinic at approximately 4:30 p.m. However, security camera footage recovered from the building shows Mazonakis entering much earlier, at around 1:00 p.m.
Detectives are scrutinizing the three-and-a-half-hour gap to reconstruct the sequence of events from the moment the artist arrived until his physical collapse.
Forensic analysis of medical equipment
Forensic officers are examining medical equipment seized from the Kolonaki clinic, focusing on a plasmapheresis machine used during the visit. Plasmapheresis is a medical procedure that separates blood plasma from blood cells.
Specialists from the Criminal Investigation Directorate gained access to the machine's internal software and recovered digital operational logs. The data indicates that the machine was operated for approximately 45 minutes on the day of the incident.
Authorities are evaluating whether the fatal cardiac arrest occurred while the machine was actively running. Police noted that this scenario remains a hypothesis under active investigation and no definitive medical conclusion has been reached.
Evidence seized from clinic and residence
Prior to searching the singer's home in Voula, police conducted searches at both the Karneadou Street practice and the doctors' private residence in the northern Athens suburb of Psychiko.
Officers confiscated four large files and a bag of physical material from the clinic. The seized items include medical preparations, patient records, specialized clinical materials, operational licenses, doctor certifications, and staff documentation.
Investigators also secured the digital records extracted from the plasmapheresis machine alongside hours of security camera footage gathered from surrounding locations.
Family requests phone record disclosure
Family lawyer Charalampos Lykoudis announced that the family is seeking a full investigation into the circumstances of the singer's death. Lykoudis stated that the family will formally request the judicial lifting of telephone confidentiality to examine communication logs of key individuals involved in the case.
The official autopsy and necropsy on the singer's body have been postponed. The family has appointed an independent technical advisor to represent them during the forensic examination.
Authorities are combining witness statements, forensic physical evidence, surveillance footage, and digital logs to establish the exact cause and timeline of events prior to the singer's collapse.
