According to officials with the East Ramapo Central School District, as students were dismissed for the weekend, school security responded to reports of an argument among students in the parking lot of the school.
The Spring Valley Police Department School Resource Officer and school security quickly responded and broke up the dispute, district officials said.
Two students suffered lacerations from a knife and a third student suffered minor abrasions to the face, they added.
One individual was taken into custody and an investigation is currently ongoing.
