Foued Mohamed Aggad, a 23-year-old man from the eastern French city of Strasbourg, has been identified as the third bomber involved in last month’s attacks at Paris’s Bataclan concert hall, police sources said Wednesday. A series of well-coordinated shootings and suicide bombings across the French capital killed 130 people and injured hundreds others on Nov. 13.

A French legal official reportedly said that Aggad left for Syria in 2013 along with his brother and a group of friends. A source close to the investigation said that most of them were arrested last year after they returned to France, but Aggad continued to stay in Syria, parts of which are controlled by the Islamic State group, also known as ISIS, according to Agence France-Presse. Aggad was identified after his DNA was matched with those of his family members, the police source said.

Three terrorists, who had pledged allegiance to ISIS, arrived at the back of the hall during an Eagles of Death Metal show last month at the Bataclan concert hall and opened fire on the crowd using semiautomatic rifles, killing 90 people and wounding dozens of others. Two of the attackers blew themselves up while the third was shot by police.

The Bataclan assault was part of a series of attacks across Paris on Nov. 13, targeting cafes, restaurants and a sports stadium. ISIS claimed responsibility for the Paris attacks, prompting the French government to impose a state of emergency for three months.

Two others who blew themselves up at the Bataclan music venue were identified as Frenchmen Omar Ismail Mostefai, 29, who lived in Chartres, southwest of Paris, and Samy Amimour, 28, from Drancy, northeast of Paris. So far, the attackers involved in the Paris attacks were either from France or Belgium, and were all native French speakers.
