NAPLES, Fla.- A Naples man took the law into his own hands, stopping a man who was allegedly breaking into his truck this weekend.

The homeowner said he often has trouble sleeping. Late Saturday night, he got up to take a walk on his property and he brought a flash light with him so he could see. Little did he know, he'd be using it to stop a burglar in the act.

Greg, a Naples resident for the last 30 years, says his adrenaline was pumping on Saturday night.

"I just kind of reacted. I've been robbed here more than once and I'm tired of it," he said. "I saw a little, white car coming down the street, and he proceeded to the end of the street, slowly, and stopped, turned around, which he didn't belong on the street. It's a dead end street."

Officials say 22-year-old Alesi Fernandez was getting into Greg's truck.

"I gave him about 10 seconds, and I came up on top of him, slammed the door on him, hit him in the head a couple times with the flashlight, and then took control of him, and actually impacted his head into the bumper of the truck to get more control of him," Greg said.

Greg didn't know if he was armed or if there was someone else in the car, but he did think to take Fernandez's wallet once he knocked him out cold. He turned off the car, locked the doors and took the keys with him as he called 911.

Fernandez was awake when he came back outside, where Greg held him until deputies arrived.

Fernandez has a long record of burglary and grand theft, and he had just graduated from the county's drug court program.
