A North Carolina woman is in hot water after she allegedly pulled a knife on two 13-year-old boys she believed was bullying her son on Friday, WSOC-TV reports.

Olga Cortez is accused of following her son’s bus to Coulwood Middle School in Charlotte and then reporting the two suspected bullies to school staff.

Cortez reportedly became irate after one of the boys reportedly assaulted her physically, at which point she took out a knife and began thrashing it through the air, according to police. School employees were able to get control of Cortez, who later put the knife in her vehicle.

It is believed no one was physically injured from the knife.

Police responded to the school after a 911 caller reported a woman with a knife was on the school campus. Authorities charged Cortez with three counts of assault using a deadly weapon and one count of possessing a weapon at a school.

The two alleged bullies were charged with simple assault and public affray; Cortez’s son also was charged with public affray, WCNC-TV reports. Cortez was released from jail on Friday evening and her son was suspended.

Coulwood Middle School entered a “self-contained mode” because of the incident, according to the television station.

The principal later issued the following message message to parents.

“Before school started, we went into self-contained mode due to police activity in the bus parking lot. (Charlotte-Mecklenburg Police Department) responded and arrested a suspect. No students or staff were injured.”
