Authorities were investigating the robbery of an Aurora bank Tuesday afternoon on the city's near-west side.
The suspect fled with an undisclosed sum about 2:50 p.m. after he entered Associated Bank, 301 W. Galena Blvd., and demanded money from a teller, police said.
The robber was described as a black man with a slim build, about 25 to 30 years old and standing between 5 feet, 8 inches and 5 feet 9 inches. He was last seen wearing a "fishing-type hat," glasses and a white, long-sleeve shirt, according to police.
Authorities said anyone with information on the robbery should call the FBI at (312) 421-6700 or Aurora police at (630) 256-5500.
