A 13-year-old boy is under arrest after police say a school safety agent was stabbed while trying to break up a fight outside an East Flatbush middle school.

The incident happened around 3:11 p.m. Wednesday near Ralph Avenue and Beverley Road, outside I.S. 285, also known as the Meyer Levin School, which serves students in grades six through eight.

Police say a 53-year-old female school safety agent stepped in to stop a fight involving two students. During that confrontation, investigators say she was stabbed in the left leg.

EMS rushed the agent to Kings County Hospital Center, where she is now recovering.

Overnight, police confirmed a 13-year-old boy was arrested and charged with assault in connection with the incident.

Sources with the school safety union tell News 12 the school is a non-scanning building, meaning students do not go through metal detectors when entering.

Police are still working to piece together exactly what led up to the fight.
