Abdelhamid Abaaoud, 29, who led the Paris attacks, returned to scenes of the shootings and the Bataclan concert hall while the siege was still going, says the city’s prosecutor, Francois Molins. The Paris prosecutor revealed that Abaaoud’s movements were pieced together using location data from the phone he used that night, reports Sky News. The ringleader, who died when police raided his hideout last week, mingled with onlookers outside the Bataclan concert hall where 89 people were killed.
