'Caveman' thwarts store robber with step ladder

Police said a would-be robber got more than he bargained for when he tried to rob a Quik Thrift store in Acworth, Georgia with a knife.

A quick-thinking customer, known only as "Caveman," grabbed a step ladder and hit the suspect at least once Monday. The customer chased the suspect from the store using the ladder as protection.

Police said the suspect had threatened to cut the store clerk's neck if money wasn't handed over. Police said the suspect escaped with some money, but he dropped much of it when he was hit with the ladder.

Police are still searching for the suspect.

'Caveman' in action!
