A woman in Western New York has been arrested for threatening to “body slam” an elementary school principal.

The Buffalo News reports police were called to the Henry J. Kalfas Magnet Elementary School in Niagara Falls, N.Y., when a mother “became aggressive" during a parent-teacher conference with her child’s teacher and the school principal Wednesday. Principal Italo J. Baldassarre told police the mother, identified as Laquonda T. Crittenden Howard, accused the teacher of mistreating her son and began shouting obscenities.

“The meeting quickly deteriorated and Laquonda began shouting obscenities, stating to staff, ‘You need to get your (expletive) teachers in line,’ and, ‘You don’t know what the (expletive) you are doing,’” the police report said.

Baldassarre told Crittenden Howard to leave, but she refused and continued shouting. According to the Niagara Gazette, Baldassare said the child’s father had to hold Crittenden Howard back at one point.

According to the police report, Crittenden Howard then entered an area of the school where parents were not allowed, with signs indicating the restrictions, and took her son out of the classroom.

“You don’t know who you’re messing with, I will (expletive) body slam you,” Crittenden Howard told Baldassare before leaving.

The Niagara Gazette reports Baldassare told police he feared for his safety, and also said the woman has tried to attack him in the past.

Crittenden Howard, 28, was charged with third-degree menacing and criminal trespassing. She was also banned from the school grounds, police said.
