Surveillance video obtained Friday shows a clerk at an Ohio convenience store shooting and wounding a would-be armed robber.

“It was really tough,” the clerk told Fox 28 Columbus, which aired the video. “It’s not easy to shoot someone, especially with someone who never had to deal with guns.”

Emanuel Hamm, 27, was charged with aggravated robbery, according to the station. He reportedly suffered a gunshot wound to his hand.

The clerk was behind the counter when authorities say Hamm walked into the M & M food market and gas station in Darbydale Thursday night with a handgun, the station reported.

The clerk told the station Hamm looked suspicious to him.

The video shows the clerk reaching in his back pocket for his gun as Hamm nears the counter.

“As soon as I saw the gun, I pulled mine and I shot him,” the clerk said.

In the video there is gunfire and then Hamm is seen running towards the door.

The clerk didn’t want to be identified, according to the station.

He expressed sympathy for the man he shot.

“I feel bad for him, but I didn’t have a choice,” the clerk told the station.
