RALEIGH — Police arrested a 19-year-old woman Monday on charges that she inflicted burns on her 3-month-old cousin last month while she was supervising the infant.

According to an arrest warrant, Mercedes Evette Norman of 3701 Marshlane Way in Raleigh was responsible for “8 percent body burns to the child’s buttocks and left ankle and thigh” on Jan. 23.

The charge of intentional child abuse inflicting serious personal injury involves putting the baby into bath water that was too hot, police spokesman Jim Sughrue said.

Detectives are continuing to investigate, he added.

The warrant says that the baby is Norman’s second cousin.

Norman was being held on $100,000 bond at the Wake County Detention Center.
