A key judge in the trial of late Argentine football superstar Diego Maradona's medical team stepped down on Tuesday, amid a scandal that has thrown the future of the high-profile case into doubt.

Argentine police fought running battles on Wednesday with hundreds of football fans and anti-austerity marchers, during a weekly protest by pensioners in Buenos Aires.

Seven Argentines went on trial Tuesday accused of homicide for their alleged role in what prosecutors called the "horror theater" of football legend Diego Maradona's death four years ago.

Four years after the death of Argentine football legend Diego Maradona, seven healthcare professionals will go on trial next week accused of negligence during his final days.
