Even on the Way of St. James, clothes don't make the man. Since a complaint was filed on September 28, a man in his forties, who presents himself as a pilgrim, has been actively sought by the Saint-Savin gendarmerie. He is suspected of being the perpetrator of several thefts of credit cards and cars from hosts on the way.
To carry out his misdeeds, the individual pretends to need to rest on the long road that takes him to Spain and manages to invite himself to his victims' homes for a few days, or even several weeks. "Generally, he gets close to women, gains their trust, works and contributes to certain expenses while he does his reconnaissance, then he leaves with the credit card, his code and a car," a source close to the case tells Le Figaro.
The Fédération française des associations des chemins de Saint-Jacques-de-Compostelle is warning people about the man too.
