Two banks about two miles apart were robbed within 10 minutes of each other Wednesday morning on the Northwest Side.
The first robbery occurred at 10:13 a.m. at the First Merit Bank branch in the 7200 block of West Addison Street, FBI spokeswoman Joan Hyde said.
A lone male wearing a dark baseball cap and dark plaid shirt displayed a handgun and vaulted the bank counter. He fled with an undetermined amount of cash, but a possible suspect is in custody, Hyde said.
The second robbery occurred about 10 minutes later at a TCF Bank branch in the 7300 block of West Foster Avenue, Hyde said. A lone male wearing a white head covering and dark glasses passed a note demanding cash to the teller. He fled on foot with an undetermined amount of cash.
There were no injuries during either robbery, according to Hyde, who said it was unclear whether the robberies were related.
Anyone with information should contact the FBI at (312) 421-6700 or Chicago Police.
