COLUMBUS: Federal labor officials say the operators of two Mexican groceries in Ohio and a small chain of restaurants in the Columbus area have been fined and have agreed to pay back wages to more than 250 employees.

The U.S. Labor Department says the businesses failed to pay employees enough for the hours they worked and for overtime.

They are Los Tres Amigos Supermarket in Cincinnati, La Plaza Tapatia Supermarket in Columbus and three Jalapenos Mexican Restaurants in the Columbus area.

Investigators also say the employers kept two sets of records and gave false documents to them.

The labor department says the businesses agreed to pay a total of $230,000 for back wages and $30,000 in fines.
