Diego Maradona’s doctor Leopoldo Luque is being investigated for involuntary manslaughter four days after the Argentine football legend’s death.

Earlier in the day prosecutors in San Isidro said they were investigating Leopoldo Luque while Argentine television showed police raiding the doctor’s surgery and home.

Luque said he did “everything he could, up to the impossible” and considered himself a “friend” of Maradona and saw him “as a father, not as a patient”.

“He should have gone to a rehabilitation center. He didn’t want to,” said Luque.
