Bob Bertino didn't want the man pointing a shotgun at him to ruin his Christmas.

Bertino was starting work Wednesday at his store, Crazy Bob's Electronics on Rivers Avenue in North Charleston, when a man walked through the door around 8:10 a.m. The man was wearing a hooded sweatshirt and a bandanna, and he was carrying a bag.

Bertino knew he was being robbed. He offered the man a tip jar sitting on the counter. But that wasn't enough.

"He cocked his shotgun and put it in my face," Bertino said. "He said, 'I want all your money, all your computers and all your gold.' I said that's not going to happen."

The gunman pointed the shotgun, which was equipped with a pistol grip, over Bertino's right shoulder. That's when Bertino made his move.

"I grabbed the gun and jerked it down," he said. "I got him in a headlock, dragged him over toward the door and let him go."

Officers from the North Charleston Police Department traced a license plate from the getaway vehicle to a home on Hallmark Drive in Goose Creek. Late Wednesday, that's where they arrested 32-year-old Bernard William Reese.

Reese faces a charge of attempted armed robbery, a felony punishable by up to 20 years in prison. He was jailed in lieu of $150,000 bail.

"Nobody was hurt," police spokesman Spencer Pryor said. "It was a lucky day for both of them."
