Argentine prosecutors were investigating the circumstances surrounding the death of Diego Maradona and whether it could have involved medical negligence.
Maradona’s lawyer, Matias Morla, had earlier called for an investigation into claims that ambulances took more than half an hour to reach the football star’s house in response to an emergency call on the day of his death.
A preliminary autopsy report established that Maradona died in his sleep at noon on Wednesday of “acute lung edema and chronic heart failure.”
The prosecutor’s office in Buenos Aires has opened a file entitled “Maradona, Diego. Determination of the cause of death.”
The 60-year-old Argentine football legend was receiving round-the-clock medical care at a house in a gated community in Tigre, north of Buenos Aires, where he was recuperating from surgery to remove a clot on his brain in early November.
