The family of a 12-year-old girl who was physically assaulted by another child in Douglass Hills, Kentucky is reportedly taking action against the school system. The girl’s parents claim they weren't notified of the attack at Crosby Middle School until 10 days later, when a disturbing video of the incident surfaced. The confrontation reportedly began when the girl sat in another child’s seat.

According to the girl’s mother, Hollie King, the 12-year-old suffered multiple head injuries and a separated shoulder. In the graphic video, the attacker can be seen repeatedly throwing blows at the girls head while she is dragged on the floor in the school bathroom. She has reportedly returned to school with her arm in a sling.

The incident allegedly occurred April 14, but the Kings were not notified by the school until Monday, WAVE 3 News reported Wednesday. According to the King family, they weren’t shown the video of their daughter’s attack until the following Wednesday, at which point they took the girl to the emergency room and filed a police report.

"When I took her to the emergency room, they told me she’s lucky she didn’t have internal brain bleeding," King told WAVE 3 News.

The King family called a press conference Wednesday to publically address the incident alongside their attorney Teddy Gordon, WAVE 3 News reports. The Kings are the most recent additions to a pending lawsuit filed in December by six families who are suing the Jefferson County Public School system, claiming that Cosby Middle School allows bullying to occur on its grounds.

"The lawsuit lists the Jefferson County School Board, Superintendent Donna Hargens, along with the principal, two assistant principals and three counselors at Crosby Middle School as the defendants," according to WAVE 3 News.

WAVE 3 reports that Kim Seewer, whose son attends Crosby Middle School, said during a Dec. 15 press conference that her son "was intimidated, humiliated, he threw up and cried and begged not to go to school."

Another parent, Bethany Littlefield, said that the middle school "is a survival of the fittest," and added, "My child wouldn't even stop at his locker because of how crazy the hallways are."

"The only information I have at this time on the incident at Crosby Middle School is what has been circulating in the media," Douglass Hills Mayor Bonnie Jung told International Business Times by email. "It is hard to watch and very concerning. I know that Crosby Middle School has been a great part of our City for many years. The City stands ready to assist in any way to help the school, students and families to make Crosby the best it can be."

Neither Gordon nor a representative of the school immediately returned IBTimes’ request for comment.
