The man is said to be the youngest of the three men suspected in the terror attack of the French satirical magazine.
It has been reported police were looking for brothers Said, 34 and Chérif Kouachi, 32.The third suspect named is 18-year-old Hamyd Mourad.
This morning reports suggest Mourad handed himself in at a police station in Charleville-Mezieres, which is situated approximately 145 miles northeast of Paris. This horrific attack is said to be among one of the deadliest post-war attacks in France.
The three men, who officials say are linked to a Yemeni terror network, are known to the French intelligence services.
Chérif, Paris-born, was reportedly sentenced to three years in prison for helping to funnel prospective jihadi fighters from France to Iraq, the Associated Press reported in 2008.
Metro News in Paris reports, Hamyd, who is suspected of being the getaway driver, just left high school in Charleville-Mézieres, and has been homeless since graduating.
The French President had referred to the hooded gunman attack as an act of terrorism. The three men wielding Kalashnikovs walked into the offices of Charlie Hebdo yesterday morning.
The magazine has caused controversy in the past for its depiction of the muslim prophet Muhammed in cartoons, which outraged some.
Their offices were firebombed in in 2011 following one such cartoon, to which their response was a further front cover depicting the prophet and the line: "Love it stronger than hate."
French President Francois Hollande visited the scene of the murders on Wednesday morning and said there was no doubt this was an act of terrorism. He added that France would not have their free speech threatened, and they ‘will fight these threats and punish the attackers.’
