The state is investigating companies working to finish the elementary school in Unity over allegations that some subcontractors are using workers living in the country illegally.
James Craig, commissioner for the New Hampshire Department of Labor, tells the Eagle Times investigators were at the job site last week. Authorities say it was sparked by the arrest of two men from Mexico who were held on immigration detainers.
Lebanon-based Trumbull-Nelson Construction Co. took over construction of the new school in January after the original architect was removed. The long-delayed building is expected to open in September.
Ron Bauer, executive vice president of Trumbull-Nelson, has said the company has no control over who gets hired by the subcontractors.
