The robbery happened just after 1:00 p.m. Wednesday at Associated Bank on the 3700 block of South Kinnickinnic Drive.

A masked armed robber came charging into the bank, but a customer sprang into action.

Raw video from the bank shows that the person's face was covered, with a bag in hand.

The suspect points a gun at the teller, demanding money.
St. Francis Police are looking for a suspect who held up a bank, but was foiled - and tackled - by a customer.

The customer behind in the background wasn't having any of it, and he tackled the masked robber, who ran out of the bank.

The armed robber is believed to be about 5' 5" to 5' 8", stocky, wearing what appears to be a hooded sweatshirt with a dark-colored lions crest on the back.

Police believe the robber took off in a 1984 Oldsmobile 88 four-door sedan, tan in color, with a disabled license plate number of 86816D.
