Argentine prosecutors are investigating Diego Maradona’s doctor for possible manslaughter following the footballing legend’s death four days ago.
Police in Buenos Aires have searched the house and private clinic of Leopoldo Luque as they try to establish if there was negligence in Maradona’s treatment following surgery.
The 60-year-old died of a heart attack at his home where he was recuperating.
His daughters have pressed for details about their father’s medication.
Maradona had a successful operation on a brain blood clot earlier in November and had been due to be treated for alcohol dependency.
In an emotional press conference on Sunday, Dr Luque – who was the footballer’s personal physician – cried, saying he had done all he could to save the life of a friend. He said Maradona had been very sad lately.
Dr Luque added that he was co-operating with the authorities.
