A DeKalb County man who went home for lunch arrived to find three people had broken into his home, authorities said.

The homeowner, who has not been identified, received a call while on the way home that the alarm at his residence had been activated. When he got to the house, he walked around the back of the residence and saw three people standing inside, DeKalb police Capt. Stephen Fore said.

“He called 911 from a cell phone as he observed people inside the home,” Fore said. “As he was on the phone with 911, the three suspects exited the rear of his home and ran toward him.”

That is when the homeowner pulled out his gun and shot one of the suspects, police said. The remaining two suspects fled on foot.

The suspect who was shot was picked up in the area and taken to Grady Memorial Hospital for treatment. The suspect had non-life-threatening injuries, Fore said.

It is not clear if the two suspects who fled took anything from the home, but the residence had been ransacked, police said.

Fore said this residence had been broken into before, but he did not have details of the previous incident.
