A man who tried to rob a convenience store had his plan bizarrely foiled because the cashier cut her finger.

The armed thief was foiled at a Madison, Wisconsin, shop when he cut the shop owner's finger.

Unfortunately for him, her wound made it impossible for him to open the cash drawer with the register's computer touch screen because it could not recognise her fingerprint.

Even though the callous thief was unsuccessful in running away with the shop's money, he grabbed some cigarettes and fled to a getaway car.

The suspect - who was armed with a box cutter and wearing a mask - is currently still at large

In the United States, a total six per cent of robberies take place in convenience stores.
