The FBI said a man with a gun robbed the CitiBank near Michigan Avenue and Grand Avenue Friday morning.
Investigators believe the same man robbed or attempted to rob other banks along Michigan Avenue each month starting in September.
The first attempted robbery took place on Sept. 19 at 100 South Michigan Avenue. The second attempted robbery took place on Oct. 11 at 180 North Michigan Avenue. Less than a month later, on Nov. 7, the suspect returned to 180 North Michigan Avenue and successfully robbed the bank, the FBI said.
The suspect is described as a Black man with a medium build and a black and gray goatee, wearing a red/orange hooded jacket, a blue and yellow "Michigan" zip-up jacket underneath, black pants, a blue beanie cap and black and white Nike shoes.
