Authorities say a Georgia police officer shot and injured a man who refused to drop a handgun.

The Georgia Bureau of Investigation said in a news release that Henry County police asked the agency to investigate the shooting, which happened early Wednesday at a Stockbridge home.

The GBI says someone called 911 a little before midnight Tuesday to report hearing a woman yelling for help and gunshots. The GBI says a preliminary review of the 911 call indicates the three officers who responded went to the wrong home.

The GBI says the officers were met by the homeowner, 63-year-old William Powell, who had a handgun. One of the officers shot Powell in the neck when he didn't obey officers' commands to drop the gun.

Powell was taken to a hospital for treatment. His condition was unknown.
