Florence Police Chief Anson Shells said a woman called 911 around 3:30 a.m. today after hearing a noise in her apartment and finding a bedroom door locked.
Investigators say the officer found the window to the bedroom open and climbed inside. He opened a closet and was so startled by a man inside he dropped his flashlight, plunging the room into darkness.
Shells says the officer then fired one shot that hit the man in the shoulder. He is expected to recover.
Shells says the officer is a 26-year veteran of the force and will remain on leave while the State Law Enforcement Division investigates.
