The Office of Investigations (OI) conducts investigations throughout the United States in response to complaints or allegations regarding violations of Federal law.  Special agents identify and investigate cases of waste, fraud and abuse in agency programs and operations, and refer cases for prosecution and monetary recovery action.  In Fiscal Year 2004, OI is staffed with 17 special agents and five support staff.

Typical cases fall within the following categories:

• false reporting by railroad employers,
• theft and fraudulent cashing of U.S. Treasury checks or conversion of U.S. Treasury electronic fund transfers by someone other than an authorized RRB annuitant,
• railroad employees claiming and receiving unemployment or sickness insurance benefits while working and receiving wages from an employer, and
• individuals receiving disability benefits and earning in excess of the allowed amount

OI maintains two field offices, one in the agency's headquarters in Chicago, IL and one in Philadelphia, PA.  Investigations in sixteen eastern states as well as the District of Columbia are conducted by agents located in Philadelphia.  Cases in the remaining states are handled by the Chicago field office.
