MOBILE, Alabama -- A homeowner fended off three armed men, who appeared to be attempting a home invasion on Thursday night, after he grabbed a shotgun in his defense, said a Mobile Police Department spokesman.

On Thursday night, there was a knock on the door of a home on the 2000 block of Marian Drive, said Officer Terence Perkins, spokesman for MPD. When the door was answered by a person related to the home's owner, that person was greeted by three men armed with handguns who proceeded to force their way into the home, Perkins said.

"A resident was able to run upstairs and alert his dad," Perkins said. The homeowner grabbed his shotgun, ran downstairs and racked it. The suspects fled before he could aim at them, Perkins said.

Police were called to the scene around 8:20 p.m., he said.

He could not say exactly how many people were in the home at the time of the confrontation, although he acknowledged at least the homeowner and his son were in the residence.

Nothing was stolen and no injuries were reported in the attack.

"This is a totally isolated incident," Perkins said. "We do not believe this is a random act."

He could not provide a full description of the suspects, although he said the investigation is ongoing.

Anyone with information on the suspects or the home invasion can contact MPD at 251-208-7211.
