Muslim terrorist from today’s scheduled attack in Paris was a known wolf

French authorities say the man who rammed a car full of explosives into a police van on the Champs-Elysees on Monday was already flagged as a potential terrorist, according to reports.

The attacker was a 31-year-old man from the Paris suburb of Argenteuil who has an “S” file — which means cops believed he had possible ties to extremism, officials told the AP.

The man died in the collision, police said.
