The office or person receiving such a report shall refer it to the appropriate office of the Wage and Hour Division, for the region or area in which the reported violation is alleged to have occurred.

(d) In case of disobedience to a subpena, the Secretary may invoke the aid of a United States District Court which is authorized to issue an order requiring the person to obey such subpena.
