SMRYNA, Ga. (AP) — Police in Georgia say a day care worker has body-slammed a toddler, bloodying the 16-month-old's lip and shirt.

News outlets report 20-year-old Jonee Nicole Hamilton was arrested Tuesday on charges including child cruelty and aggravated assault. Smryna police says the Oxford Babies worker was upset last week when the child refused to nap and so shoved the toddler's head into a floor mat.

A police report says Hamilton then picked the child up and slammed them into the mat, busting the child's lip. Officer Heather Knight says the child was treated at a hospital.

Hamilton passed a background check when she was hired in September. She has since been fired.

Knight says police are reviewing the day care's surveillance videos.
