The search began Sunday morning.
Prosecutors behind the order, which was said to have been sanctioned by a judge, have reportedly tried to determine whether the football legend was the victim of medical negligence.
The dramatic twist in the investigation into Maradona’s death follows overnight reports that he rowed with personal doctor Leopoldo Luque in the days leading up to his heart failure last Wednesday.
Luque is at home during the search on the outskirts of Buenos Aires.
Local TV channels broadcast footage of the police entering the Luque clinic.
The searches were ordered after Maradona’s daughters, Dalma and Giannina, made statements and questioned whether the medicine their father was receiving was appropriate.
Argentine media report that Luque could be questioned as an “imputado”, someone who is officially investigated on suspicion of mala praxis or neglect, rather than as a mere witness.
There is no indication that he will be charged with any crime at this stage of the investigation.
Maradona’s lawyer Matias Morla last week called for a high-level investigation into the emergency response to the death of the retired footballer.
Matias Morla said the first ambulance took more than half an hour to reach the rented house north of Buenos Aires, where the former Naples and Barcelona star suffered from heart failure.
He called the delay “criminal idiocy”.
Mr Morla also complained that Maradona had not received a medical check-up in the 12 hours before his death, appearing to put more pressure on former footballer Leopoldo Luque’s personal doctor.
It later emerged that the first ambulance took 11 minutes to reach the closed private estate of San Andres near Buenos Aires where Maradona had moved after leaving the hospital on November 11 after her brain blood clot surgery.
On Saturday, it appeared that Maradona’s nurse had admitted that she had lied about a morning check-up in Maradona.
The sensational confession added more mystery to the circumstances surrounding his untimely death.
Initial reports indicated that a 24-year-old nephew who lived with him at the San Andres home was the last person to see him alive at breakfast on the day Diego died.
He reportedly told his loved one, “I don’t feel well” before going back to bed and dying in his sleep before investigators were told he never got up on Wednesday to eat anything. is.
Diego’s nephew told investigators he last saw him when he went to bed around 11 p.m. Tuesday.
An uneaten late-night sandwich was among the items found in his room by police.
A night nurse told investigators he saw Maradona “sleeping and breathing normally in her bed” around 6.30am Wednesday.
A report in the hands of state prosecutors investigating the death of the retired footballer, leaked to Argentine media and signed by a nurse named locally Dahiana Gisela Madrid who took over at around the same time, says, “At 6:30 am I started my shift and the patient was resting.
“At 7:30 am, we hear him move into his room. At 8:30 am, he continues to rest. At 9:20 a.m., he refused to have his vital signs monitored.
Private medical firm Medidom’s health report is now the focus of an ongoing investigation after the nurse allegedly told investigators she never entered Diego’s room on the morning of his death to monitor him .
Local Telam news agency, citing forensic sources in a report widely covered in the Argentinian press, said the nurse claimed in her second affidavit that she was “forced to lie” for the Medidom report. .
“What the witness added in this second statement is that she was forced to write in a report for Medidom, where she is part of the nursing team helping people receiving medical care at home, who ‘She had tried to monitor Maradona’s vital signs when the reality was she let him rest,’ the report says.
It was not very clear whether she claimed that her bosses had forced her to file the “fake” report, fearing that she would be charged with negligence following Maradona’s death, or that her hand had been forced. by others.
A psychiatrist and psychologist who was part of Diego Maradona’s care team, named Susana Cosachov and Carlos Diaz, reportedly entered the room just before noon and made several unsuccessful attempts to revive him before calling 999.
A recording of the call that Maradona’s personal doctor, Leopoldo Luque, made to the emergency services, stating that he had suffered suspected cardiac arrest, has already been leaked to Argentine media.
The former Naples and Barcelona star, who was just 60, was pronounced dead on Wednesday around noon.
The first post-mortem results revealed that the recovering drug addict, who also had alcohol problems, had suffered from heart failure which caused pulmonary edema.
Doctors have also reportedly detected dilated cardiomyopathy, a medical condition in which the heart muscle weakens and expands and cannot pump enough blood to the rest of the body.
Pulmonary edema, fluid build-up in lung tissue and airspaces, is caused in most cases by heart problems.
State prosecutors are analyzing CCTV footage from cameras in the estate where Diego lived and cell phones from nurses who treated him in the hours before his death.
They said that after his death, in their initial comments, there was no indication of any criminality and so far said everything suggested that the former footballer had died of natural causes.
Leopoldo Luque was not in the rented house that Maradona was using when he died.
Diego Maradona dies at 60
A forensic source told respected Argentinian newspaper La Nacion: “As Luque was Maradona’s personal physician, the decision was made to search his home and perform surgery to search for documents that could determine whether, during treatment of Maradona at home, there were irregularities. ”
It is believed that investigators are seeking details of the drug being administered to Maradona as well as her medical records and other documents that could play a key role in the investigation.
Thirty police officers and magistrates are said to be at Luque’s home and another at his professional address.
