SAN ANTONIO, Texas - Federal authorities have recovered thousands of dollars in back wages and civil penalties from the operators of three San Antonio-area bakeries after an investigation uncovered child labor, minimum wage, and overtime violations.

What we know: The U.S. Department of Labor's Wage and Hour Division announced the findings following an investigation into three La Panaderia Bakery & Caf locations operated under Tequila Almond Croissant LLC, Pan Dulce LLC, and SA Bakery Co. LLC. In total, the businesses paid more than $45,000 in back wages and penalties, according to the Department of Labor.

Investigators found that the employers violated child labor provisions of the Fair Labor Standards Act by employing a 13-year-old-below the legal age for employment-and allowing a 15-year-old minor to work overnight shifts, which is prohibited for 14- and 15-year-olds.
