The FBI is asking the public for help in identifying the individual who carried out an armed takeover-style bank robbery yesterday morning. Robert J. Holley, Special Agent in Charge of the Chicago Office of the FBI, announced today that a reward of up to $10,000 is being offered for information leading to the identification and arrest of the individual who threatened bank employees with a large knife as he robbed the TCF Bank branch located at 927 North Green Bay Road in Waukegan.

During the robbery, which occurred just after 10:00 a.m. on May 21, 2014, the robber entered the bank and approached a bank employee at a teller window. He then displayed the knife and led that bank employee and one other to the bank’s vault. After taking cash from the vault, the robber fled on foot, headed in an easterly direction. Witnesses described him as a black male, 25 to 30 years old and approximately 5’7” tall with a medium build. He wore a black knit cap, a large black hooded sweatshirt, and dark colored jeans, and he carried a light-colored backpack, into which he placed the money he took from the vault.

Anyone recognizing this individual or having information about the robberies is asked to call the Chicago FBI at (312) 421-6700 or local law enforcement.
