The Aurora Police Department responded to a hold up alarm at about 1 p.m. at the TCF Bank located inside the Jewel Food Store, 1270 N. Lake St.
An African American male presented a female teller with a note demanding money, police said in a news release. The suspect appeared to be 20 to 25 years old, approximately 5'9" to 6' tall and weighing between 140 and 160 pounds.
Officials said a second African American male stood near the bank counter and allegedly acted as a "look out." This suspect appeared to be 25 to 30 years old, and fit the same physical description as the other suspect.
The teller handed over an undisclosed amount of cash, and both men fled the building on foot in an unknown direction, police said.
Officials said neither suspect wore a mask, nor did they display or imply they had weapons.
No injuries were reported.
Aurora Police, the FBI and Oswego Police are investigating if this robbery is connected to an incident that occurred in Oswego on December 20 where a TCF Bank that was also inside of a Jewel Food Store was robbed by two men with similar descriptions.
