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.

Two guards were killed when armed assailants helped Mohamed Amra escape from a prison convoy last May, prompting a high-profile search.

Arrested in Romania and returned to France on Tuesday evening, drug trafficker and fugitive Mohamed Amra has been indicted for 'murder, attempted murder, escape, theft and concealment of theft,' as well as for 'criminal conspiracy.
