French media has identified one of the terrorists behind a string of deadly Paris attacks on Friday night as Ismail Omar Mostefai, a 29-year-old Frenchman from the southern Paris suburb of Courcouronnes. 

Mostefai was living in Chartres up until three years ago, said Jean Pierre Gorges, who is mayor of the town located 60 miles southwest of Paris as well as a member of French Parliament. 

Knowledge of his whereabouts trails off after 2012. 

According to Paris prosecutor Francois Moulins, Mostefai had been flagged as possibly being close to radical Islam, but had no known links to terrorism.

“He was not in prison – though police began to notice him and he was convicted eight times between the years 2004 and 2010. That same year he was placed on a black list for his extreme behavior, but he was never classified as a member of an extremist group.”

Mostefai’s body was found at the Bataclan music hall, where 89 people were shot dead Friday when three gunmen wearing suicide vests opened fire on spectators, in the bloodiest of the attacks in Paris.

A finger found on the scene was reportedly matched to police fingerprint records. 

Police on Saturday night also took into custody Mostefai’s father and brother and were searching their homes, a source close to the probe told AFP.
