WATCH: Store owner takes down armed robber

A small business owner fought off an armed robber in California and the whole thing was caught on surveillance video.

Police say the man in a black hoodie walked into Simon's Market in Venice and pointed a gun at the shop owner and the cashier. The owner, though, waves his hand at the gunman as the cashier begins to empty the register.

When the gunman's back is to the shop owner, the owner springs into action and wrestles the would-be robber down on the ground and right out of the store.

The men struggle for the gun outside the store, but the thief just runs off and the shop owner walks back inside.

Police are investigating but say they don't recommend anyone try to fight off an armed robber on their own.
