Argentine prosecutors are investigating Diego Maradona's doctor for possible manslaughter following the footballing legend's death four days ago, APA reports citing BBC.
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.
Dr Luque denies wrongdoing and says he is co-operating with the inquiry.
Maradona had a successful operation on a brain blood clot earlier in November and had been due to be treated for alcohol dependency.
