French officials have identified one of the Paris attackers as Ismael Mostefai, a 29-year-old Frenchman who had been flagged for links to Islamic radicalism.
A French judicial official says Mostefai’s father, a brother and other family members have been detained and are being questioned Sunday.
The mayor of the French city of Chartres, Jean-Pierre Gorges, identified Mostefai as a resident in a Facebook post. The judicial official confirmed the name, speaking on condition of anonymity because the investigation is ongoing.
The Paris prosecutor said one of the attackers was a 29-year-old Frenchman born in the Chartres region who had been known to authorities for radicalism. The prosecutor said he was identified by fingerprints on a finger found in the carnage of the Paris attacks Friday night, which left at least 129 dead and hundreds wounded.
The Islamic State group has claimed responsibility for the attacks.
Meanwhile, a French judicial official says a Seat car with suspected links to Friday’s attacks has been found by police in Montreuil, a suburb 6 kilometers (nearly 4 miles) east of the French capital.
The official, who spoke on condition of anonymity because she was not publicly authorized to speak, could not immediately confirm if this was the same black Seat linked to the gun attacks on the Le Carillon bar and the Le Petit Cambodge restaurant in Rue Alibert in the city’s 10th district.
Paris prosecutor Francois Molins said Saturday that gunmen armed with automatic weapons pulled up in that model of car before opening fire, killing 15 people and injuring 10.
French prosecutors said on Saturday that three coordinated teams appeared to have carried out the wave of attacks across Paris. They were the worst in Europe since the Madrid train bombings of 2004, in which Islamists killed 191 people.
Friday’s attacks were described as an “act of war” by President Francois Hollande.
The bloodshed came as France, a founder member of the U.S.-led coalition waging air strikes against Islamic State in Iraq and Syria, was already on high alert for terrorist attacks.
