A man got away with an unknown amount of cash after robbing a Loop bank branch shortly before noon on Thursday.
The robbery took place at a bank branch in the 100 block of South Michigan Avenue about 11:50 a.m., according to police News Affairs Officer Jose Estrada. The target was a Citibank branch, according to FBI spokeswoman Joan Hyde.
The man passed a note to a teller and implied he had a weapon, then fled on foot after getting an unknown amount of cash. He did not show a weapon, police and the FBI said.
The robber was described as a black man 40-45, about 5-foot-6 with a dark complexion, wearing blue jeans, a black jacket and dark hat; and carrying a black messenger bag. He was not in custody as of early Thursday afternoon, Estrada said.
Anyone with information should contact the FBI at (312) 421-6700, or police.
