An investigation was opened for abusive canvassing after reports of a scam related to sampling of people living near the Lubrizol plant in the Rouen region.

The crackdown on fraud Wednesday said it opened an investigation for "abusive canvassing", after people residing near the Lubrizol plant in Rouen reported to have been victims of a scam related to sampling.

Direct sellers, who said they were mandated by the prefecture of Seine-Maritime to take samples and assess the pollution after the fire of the plant, billed this benefit to the inhabitants, detailed with AFP the General Directorate of competition, consumption and the repression of fraud (DGCCRF), confirming information from franceinfo.
