The U.S. Department of Labor has found two 10-year-old boys working at a McDonald's restaurant in Louisville into the wee hours of the morning.

The Wage and Hour Division of that department has led this investigation that has targeted three companies: Bauer Food LLC, Archways Richwood LLC and Bell Restaurant Group I LLC. They work with 62 branches of the famous hamburger brand in Kentucky, Indiana, Maryland and Ohio. The three franchises have been sentenced to pay $ 212,000 (192,000 euros)
