A witness on the scene said he first heard the man throwing pamphlets into the air, then saw him douse himself from a can and light himself on fire
The Associated Press cited three French officials who spoke on condition of anonymity as saying investigators were hunting for a second fugitive they believed was directly involved in last Friday's attacks but who had not been identified.
The AP story said a Nov 13 analysis of the shootings and bombings showed that one attacker had not been accounted for, in addition to Salah Abdeslam, 26, a Belgian-based Frenchman, who is on the run and is wanted on an international arrest warrant.
A justice official told Reuters: "We are in the process of determining how many there may have been. Nothing is ruled out. There's a very strong theory that there was one more, but there may have been even more."
