Greek singer Giorgos Mazonakis has died aged 54 following a cardiac arrest during a medical procedure at a private clinic in Athens.
Police arrested two doctors from the facility on felony charges of fatal exposure after investigations revealed severe discrepancies in the timeline of his emergency treatment.
The performer suffered cardiac arrest on Wednesday, September 9, while attending the Stem Cell clinic in the Kolonaki district of central Athens to undergo a scheduled plasmapheresis treatment.
Fellow Greek singer Glykeria paid tribute to Mazonakis on Thursday in a message published on her personal Instagram account, expressing profound sadness over his sudden death.
She described him as a beloved colleague and noted that she harbored fond memories of sharing the stage with him when he was taking his first steps in the music industry, adding that she was bidding him farewell with deep emotion.
Emergency response and initial medical findings
Medical reports indicate that Mazonakis experienced intense chest pain while clinicians were attempting to insert a venous catheter prior to the plasmapheresis procedure, leading immediately to cardiac arrest.
Clinic staff contacted the National Emergency Aid Centre, known as EKAB, at 16:21, prompting an emergency paramedic to arrive on a motorcycle seven minutes later at 16:28 to perform cardiopulmonary resuscitation.
An EKAB ambulance subsequently conveyed the singer to Elpis Hospital, where the vehicle arrived at 16:45, but continued resuscitation efforts proved unsuccessful and death was officially declared at 17:40.
Coroners who performed an initial post-mortem examination stated that the precise cause of death remains undetermined, with definitive findings awaiting the outcome of pending toxicological and histological tests.
Arrest of clinic doctors and allegations of delay
On Friday afternoon, two physicians from the Kolonaki clinic, identified as Ilias Theodoropoulos and Ioanna Gaka, were escorted in handcuffs from Kypseli Police Station to present themselves before the prosecutor.
Authorities filed felony charges against both doctors for fatal exposure, with the suspects scheduled to submit their formal depositions before a magistrate on Monday.
Investigators uncovered multiple contradictions in the statements provided by the accused medical personnel regarding their actions during the crisis.
Theodoropoulos claimed that he had temporarily left the premises to obtain food, while admitting that he administered two injections of adrenaline to Mazonakis after the collapse.
Gaka sought to explain inconsistencies in her account by stating that she was gripped by extreme panic during the emergency.
Police inquiries further revealed that clinic staff searched artificial intelligence tools for instructions on how to revive the patient, deleted his scheduled appointments, and took a photograph of him while he underwent the procedure.
Taxi driver testimony and legal action
A major breakthrough occurred when police located the taxi driver who transported Mazonakis to the Kolonaki clinic on the afternoon of his death.
The driver testified that he dropped the singer off at 13:55, directly contradicting assertions by clinic staff that the patient did not arrive until 16:30.
A lawyer representing the Mazonakis family stated that the singer remained unconscious for an hour and a half before clinic personnel dialed emergency services.
The family attorney announced that he will formally request prosecutors to upgrade the charges against the two doctors to manslaughter with eventual intent.
Medical specialists reviewing the case emphasized that plasmapheresis, a procedure designed to filter blood plasma, should strictly be conducted inside a hospital environment due to the risk of severe hemodynamic instability.
Funeral arrangements and industry tributes
Family members confirmed that the funeral of Giorgos Mazonakis will take place on Monday at 13:00 in the western Athens suburb of Nikaia.
In his first public remarks following the tragedy, the singer's father expressed broken-hearted grief, asking who would return his child to him.
Tributes across the Greek entertainment world continued to flood social media and public venues as colleagues remembered his legacy.
Actress Angela Gerekou posted a joint photograph of Mazonakis alongside late singer Tolis Voskopoulos, writing that she wished to believe they would meet again in heaven.
Musician Michalis Kouinelis recalled working with Mazonakis on his final recording, noting that when he told the singer the track felt heavy, Mazonakis replied that this was precisely how he felt.
Singer Ilias Vrettos shared a tribute on social media, wishing for his colleague's tormented soul to finally rest in peace.
During a concert at the Alsos Theatre, an emotional tribute unfolded during the song Ores Mikres, prompting an audience member to shout a final goodbye to Giorgos.
A controversial online comment questioning why fate had claimed Mazonakis instead of Health Minister Adonis Georgiadis ignited public debate, drawing a direct response from the minister.
