Charleston police on Thursday arrested a mother accused of throwing a knife at her daughter and beating her with a leather belt as the girl struggled to complete a homework assignment.

Ebony Martin, 25, of Bogard Street in Charleston, is charged with child neglect, Charleston County jail records show.

According to an incident report, Charleston police were called to Mitchell Math and Science Elementary School on Wednesday concerning bruises and marks found on a student. The girl's right hand was swollen, a knot was visible on her left arm and scratches were seen across the bridge of her nose, police said.

The girl told a social worker with the Department of Social Services that she received the injuries when her mother, Martin, threw a knife at her and beat her with a belt. She also received scratches on her back when her mother struck her with a fork, the report states.

Martin grew angry at the girl because she was having trouble rhyming words for a homework assignment, police said.

Martin's children were placed in the care of their grandmother in Summerville pending an investigation, the report states.

Martin is being held at the Charleston County jail pending a bond hearing.
