A Tucson convenience-store owner is being applauded after surveillance video showed him beating up a would-be robber, according to video from KVOA.

Maen Mdanat, owner of Axis Food Mart, says he watched on a monitor as the suspect asked his clerk for cash over the weekend. Recognizing trouble, Maen says he came out of his office, showed the suspect the door and was sucker punched.

Little did the man know that Maen was trained with an Army Special Forces Unit, KVOA says.

"He was comfortable walking in, showing his muscle, like I can do whatever I want," Maen said. "That's basically the message he gave me when he walked in. But I changed his idea when he walked out."

The surveillance video shows Maen punching and kicking the man, who fell to the ground. But before he left, Maen asked him if he was OK.
