Authorities say 31-year-old Precious Allen held the 15-year-old girl down in a Withrow High School classroom and told her 14-year-old daughter to hit the girl with a combination lock. Police say the victim suffered cuts and bruises in the Feb. 7 scuffle.
A grand jury indicted Allen on misdemeanor assault and trespassing charges. Her daughter is facing juvenile charges.
The Cincinnati Enquirer reports that Allen claims in a federal lawsuit filed Tuesday that her daughter was a victim of bullying and that the school intentionally deleted video that would have proved she is innocent.
