An 18-year old man sought by police over Wednesday's shooting attack at satirical weekly magazine Charlie Hebdo handed himself voluntarily to police in northeastern France, an official at the Paris prosecutor's office said.
Police are hunting three French nationals, including brothers Said Kouachi, born in 1980; Cherif
Kouachi, born in 1982; and Hamyd Mourad born in 1996, after suspected Islamist gunmen killed 12 people.
The official, who declined to identify the man, said he had turned himself in at a police station in Charleville-Mézières, in northeastern France at around 2300 GMT.
BFM TV, citing unidentified sources, said the man had decided to go to the police after seeing his name in social media. It said other arrests had taken place in circles linked to the two brothers.
The masked, black-clad suspected Islamist gunmen with assault rifles stormed the Charlie Hebdo offices yesterday Wednesday at noontime. Shouting "Allahu akbar!" as they fired, the men used fluent, unaccented French as they called out the names of specific employees.
Artist Corinne Rey told the French newspaper L'Humanite that she punched in the security code to the Charlie Hebdo offices after she and her young daughter were "brutally threatened" by the gunmen.
Eight journalists, two police officers, a maintenance worker and a visitor were killed. 11 people were wounded — four of them seriously. After fleeing, the attackers collided with another vehicle, then carjacked another car before disappearing in broad daylight.
Among the dead: the paper's editor, Stéphane Charbonnier. The staff was in an editorial meeting and the gunmen headed straight for Charbonnier — widely known by his pen name Charb — killing him and his police bodyguard first.
Artist Corinne Rey said the assault "lasted five minutes. I hid under a desk."
Charlie Hebdo has been repeatedly threatened for its caricatures of the Prophet Muhammad and other sketches. One cartoon, released in this week's issue and titled "Still No Attacks in France," had a caricature of a jihadi fighter saying "Just wait — we have until the end of January to present our New Year's wishes." Charb was the artist.
"Hey! We avenged the Prophet Muhammad! We killed Charlie Hebdo," one of the men shouted in French, according to video shot from a nearby building.
