A Drouot is caught with a stolen painting by French police provoking further investigation of the auction house, the Associated Press reports:

French police detained 12 people in a sweep of a respected Paris auction house Wednesday after finding a stolen Courbet painting worth euro900,000 ($1.3 million) at an employee’s house. Police raids on the Hotel Drouot, its warehouses and homes of employees uncovered other small artworks believed to have been stolen, a police official said.

Twelve people — an auctioneer, eight commission agents and three of their family members — were detained and questioned Wednesday by investigators from the agency for fighting art trafficking. Two were later released, the official said. The official was not authorized to be publicly named because the investigation is ongoing.
