After leaving the bank, he ran east, police said. Officers searched the area, but didn’t find anyone matching the suspect’s description.

He was described as a white man in his late 30s or early 40s, standing about 5-foot-8 with a medium build, authorities said. He was wearing a gray winter hat, a purple shoulder-length wig, a blue sweatshirt and light-colored plaid pants.

He wasn’t suspected to be a serial bank robber, according to Croon, but he was considered to be armed and dangerous.

Authorities were offering a $1,000 reward for information leading to his arrest, the FBI said.

Anyone with information about the bank robbery was asked to call the FBI’s Chicago office at (312) 421-6700 or police at (630) 469-1187.
