A man robbed a bank Friday morning in northwest suburban Bartlett.

The robbery happened about 8:45 a.m. at a TCF Bank branch at 125 E. Stearns Rd., according to the FBI. The suspect “orally demanded money” before running away southbound with an undisclosed amount of cash.

He was described as a 6-foot black man, about 20 years old with a medium build, the FBI said. He was wearing a gray New York Yankees hat, a black bandana, dark hoodie, and gray sweatpants; and was carrying a brown leather shoulder bag.

A reward of up to $1,000 is being offered for information leading to an arrest. Anyone with information should call the FBI at (312) 421-6700.
