Police say after the most recent robbery, the suspect used his victim's ATM card at a bank on Chicago's west side, allowing police to get these surveillance images of the alleged bandit.
After an attack on April 4th, a victim was able to get a good look at her attacker, which helped police develop this sketch.
Despite the fact that each of the five attacks occurred within a few blocks of one another, cops don't have conclusive evidence to link each incident.
Police are asking the public for any information regarding the Oak Park Bandit.
Cops have not ruled out the fact that they may be dealing with multiple suspects.
