No one was injured during the 11:57 a.m. robbery at the TCF Bank branch, 2520 N. Narragansett Ave., according to Chicago Police Department News Affairs Officer Robert Perez.
The man, wearing a baseball cap, a business shirt and tie and a dark jacket during the robbery according to the FBI, fled but was captured six minutes later -- at 12:07 p.m. -- after police noticed he matched the description of the robber, the officer said.
He was taken back to the bank and identified by the teller, Perez said. Federal authorities took custody of him and are leading the investigation.
According to a police report, the suspect was stopped by police because he was acting "suspiciously" and officers noticed he was wearing two sets of clothing – "sweat clothing" over another outfit.
Police searched him and found $1,467 that was taken in the robbery and a note like that presented at the bank in his left pants pocket, the report said. The suspect also had a bag containing a necktie, black hat, black jacket, and sunglasses.
According to a police source, the suspect is 64.
A spokesperson for the FBI was not immediately available Sunday afternoon to say if he was charged yet.
