Federal agents raided the East St. Louis Township offices Wednesday night.
Agents blocked the parking lot and passers-by were told that the building was closed.
Agents remained at the building, located at 6755 State St., from approximately 6:30 p.m. to 9:30 p.m.
June Hamilton Dean, a financial consultant to the township as well as Township Supervisor Oliver Hamilton Sr.’s sister and an East St. Louis councilwoman, said the federal agents were doing their jobs.
“They’re doing a thorough investigation. The township is fully cooperating because it has nothing to hide,” Dean said.
Federal authorities previously said they were investigating East St. Louis Township expenditures after News-Democrat reporters showed spending by Oliver W. Hamilton Sr. in excess of $230,000. The expenditures included trips to Las Vegas, premium car washes, steak dinners, hardware store purchases and vehicle tire purchases.
