He is described as white man in his 20s to mid-30s, standing between 5-foot-8 and 5-foot-10, weighing between 130 and 160 pounds, with a small build and a light complexion, the FBI said. In several of the robberies, he was wearing a black wig with long hair.

In the Cary robbery, the suspect implied he had a gun but didn’t display one, authorities said.

The FBI, which warned the man should be considered armed and dangerous, is offering a reward of up to $1,000 for information leading to an arrest. Anyone with information on the robbery is asked to contact the FBI at (312) 421-6700.
