SHREVEPORT, La. (AP) — Shreveport Police have arrested a 27-year-old woman after a shooting left her 3-year-old son injured.

The Times reports it happened just before 8 a.m. Saturday. Arriving officers found the toddler inside a south Shreveport home, suffering from a single gunshot wound to the arm. He was transported to University Health Hospital with injuries reported to be non-life threatening.

Investigators say the child’s mother, Chelsie Hamm, reported the shooting as an accident. She says the child picked up the loaded gun after she briefly set it down and it discharged.

Investigators believe Hamm was sleeping on the front porch and left the gun unsecured inside, where three children were. Following interviews, Hamm was arrested on one count of illegal use of a weapon. It’s unknown if she has an attorney.
