Montreal police raided the offices of Stationnement de Montréal — the agency that oversees all of the city’s parking meters — to gather evidence in an investigation.

Police officers from the EPIM Squad (Escouade de protection de l'intégrité municipale) — which has the mandate to weed out corruption, especially in bidding for public contracts — raided the offices late Wednesday afternoon on Saint-Paul Street West in Old Montreal.

Police would not say what they were looking for, but a police spokesman confirmed to the CBC’s French-language service, Radio-Canada, that the raid did not target a specific person.

“We have not made any arrests,” said Montreal police commander Ian Lafrenière.

The parking authority recently made headlines when it said it caught city employees stealing from the meters.

But police say Wednesday’s raids are part of an investigation that has been ongoing for months.
