A judicial official says a Frenchman wanted in connection with deadly terrorist attacks in Paris has been extradited from Bulgaria to France, where he is facing charges of links to terrorism.

Fritz-Joly Joachin was arrested Jan. 1 on an unrelated warrant while trying to cross from Bulgaria into Turkey. French police say that Joachin, 19, was an associate of the Kouachi brothers, who killed 12 people in an attack Jan. 7 against newspaper Charlie Hebdo.

Joachin is accused of participating in an organized crime group with a terrorist aim, and links to a network feeding fighters to Syria. The official said he arrived in France on Thursday, and is expected to appear before a judge imminently. The official spoke on condition of anonymity because of the sensitivity of the investigation.
