An Argentine ex-police officer linked to the murder of hundreds of people during the 1976-1983 military dictatorship was on a plane to Buenos Aires on Monday, after France extradited him to face trial over the disappearance of a student.
Mario Sandoval was arrested Wednesday at his home near Paris, after French authorities gave the final go-ahead for his extradition, ending an eight-year legal battle.
The 66-year-old who had been living in France since 1985 and obtained French citizenship with few aware of his full identity, was sent back on a plane that left Paris around midnight on Sunday.
"Everything happened as expected," a lawyer for the Argentine state told AFP.
Abriata was detained at the notorious ESMA navy training school in Buenos Aires, where an estimated 5,000 people were held and tortured after the military coup of 1976 -- many of them thrown from planes into the sea or the River Plate.
Sophie Thonon, a lawyer acting for Argentina, told AFP that Abriata's 92-year-old mother Beatriz Cantarini de Abriata had been "desperately waiting" for Sandoval to "explain himself before Argentine justice".
Sandoval, who has dismissed the accusations as fabrications, fled Argentina after the military junta fell.
