NASHVILLE, Tenn. – A Tennessee mother didn’t appreciate the way a principal spoke to her child, so she decked her in the face and threw a book at the woman, police allege.

Ericka Harris faces an assault charge for an alleged attack on Taylor Stratton Elementary School Principal Renita J. Perkins last week that stemmed from a conversation between Perkins, Harris’ child and another student, WKRN reports.

Perkins told police Harris’ child and another student had an issue on the school bus on the way to school last Monday and she told the children to stay away from each other or they would be banned from the bus.

Harris apparently learned of the conversation and went to the Metro Nashville school to confront Perkins, and question the principal about yelling at her child. Perkins told Harris she spoke “sternly” to the students in ordering them to keep their distance, which prompted Harris to forbid the principal from yelling at her child, according to court records cited by WZTV.

Perkins reportedly responded by informing Harris she can’t dictate how she runs the school, and the mother allegedly lashed out.

“According to the arrest warrant, that’s when Harris punched Perkins under her left eye and threw a book with a metal lock attached at her,” WKRN reports.

Witnesses confirmed the assault with police, and the incident was also recorded by school surveillance cameras.

A police report shows the principal’s left hand was swollen and she had redness under her eye after the altercation. Harris was charged with assault causing bodily injury, a Class A misdemeanor punishable by up to one year in jail and $2,500 in fines.

She was released from jail after posting bond, according to News Channel 5.

School officials declined to discuss the altercation on camera, and instead issued a prepared statement.

“We are very disappointed the dedicated educator and principal of Taylor Stratton Elementary School was assaulted by a parent on Friday, March 7. We would like to thank our school security personnel and the Metro Police Department for quickly responding to this incident,” Metro Nashville Public Schools spokesman Joe Bass wrote.

“We have enhanced the school’s security to encourage a positive academic environment that ensures the safety of all involved. Violence against employees, no matter who is the perpetrator, will not be tolerated in any way,” it continued. “Special protocols are also in place to continue offering the family involved access to all educational opportunities available in Metro Schools.”
