Charged: Tracy Lawrence was arrested on Tuesday after hitting an assistant principal at her child's elementary school

Police say a Virginia mother hit an assistant principal at her child's elementary school in the head, knocking her unconscious briefly.

Portsmouth police said in a news release that the confrontation occurred Tuesday afternoon, around 2.30pm, when 43-year-old Tracy Lawrence visited Lakeview Elementary School to speak to the assistant principal about an issue involving her child.

Police say witnesses told the investigators that Lawrence was unhappy with the assistant principal's final decision on the matter so she hit her on the head, causing her to lose consciousness.

After that, Lawrence reportedly became disorderly - shouting and drawing attention to herself.

A school resource officer called police, but by the time they arrived on the scene, Lawrence was gone.

They tracked down the woman to her home where she was arrested and charged with assault and battery and disorderly conduct.

Police say they don't believe any children witnessed the altercation.

Lawrence appeared in court on Wednesday for a bond hearing, at which point a judge ordered her held on $10,000 bail and was barred from having contact with anyone at the school.
