A notorious French fugitive who staged a deadly escape that killed two guards last year was extradited Tuesday from Romania to France, days after his arrest in Bucharest ended a nine-month international manhunt.

A suspected gangland killer described as France's "public enemy number one" was formally indicted on a slew of organised crime charges including murder before an investigating magistrate in Paris after his extradition from Romania.

Romania had vowed to hand the high-profile convict over to the French authorities, despite him contesting his detention. Handcuffed and flanked by Romanian special police forces, Amra was seen being escorted through the lobby of Bucharest airport on Tuesday. The 30-year-old convict is accused of gangland murders and drug trafficking.
