A Good Samaritan is being credited with stopping a suspected armed robber from fleeing with a woman's purse.

Surveillance video outside a Florida Walmart captured a woman who approached a lady with a cart full of groceries.

Port Saint Lucie police say the suspect showed the 65-year-old victim a knife and demanded her purse.

The woman then yelled that her purse was stolen and a man in the parking lot then ran after the thief.

The Good Samaritan tackled the robbery suspect, and was stabbed in the neck in the process.

He ended up with nine stitches but the woman's purse was recovered.

Police are looking for the purse snatcher after she got away in a pick-up truck.
