Black belt clerk strikes back at robber

When this 24-year-old man entered a convenience store in Modesto, Calif., recently, police said he was planning on robbing the store -- unaware that the man behind the cash register had a black belt in karate.

Quik Stop Night Manager Edward Petrossi said the robber pulled a knife and demanded money and that's when Petrossi went into his karate stance. He told the robber, "Bring it on."

"[I said] hey, you want my money ... right there, I chased him. He was just shocked," said Petrossi.

The would-be robber headed for the front door with Petrossi in hot pursuit.

Petrossi gives the man a kick in the back as he reaches the door.

Petrossi lands on his feet but the man was sent flying out the door.

The outside surveillance camera captures the action as it continues in the parking lot.

Petrossi follows the man outside as the man tries to head for his van.

The suspect got away, but not before the Petrossi used his cell phone camera to take a picture of the license plate of the van, which helped police catch the suspect later. 24-year-old Corey Allen Funk was arrested in Fresno for the attempted robbery. Police said that Funk is suspected in five robbery attempts in Modesto.
