The discovery of a suicide vest in a Paris suburb Monday has heightened the possibility that Europe’s most wanted man, Salah Abdeslam, abandoned his murderous mission to cause terror in the French capital before fleeing across the border into Belgium.

The vest was found by a street cleaner in a pile of rubble in Chatillon-Montrouge, on the southern edge of Paris and a considerable distance from the sites of the attacks on the Right Bank of the Seine to the north. However, authorities say data from Abdeslam’s cell phone placed him in the Chatillon-Montrouge area on the night of the Nov. 13 attacks, which killed 130 people and injured 350 others.

A police official told the Associated Press that the vest contained bolts and the same type of explosives — TATP — as those used by the ISIS attackers. A police source also told Sky News the vest had “the same configuration” as those found with the seven confirmed assailants.
