A Chester County high school student brought a BB gun into a homeroom class and shot a classmate in the chest with a plastic pellet, police said Friday.
The student was unharmed except for a "minor red mark" on his chest - and school administrators at Westtown's Rustin High School only learned about the incident after another student sent them an anonymous note, Westtown-East Goshen police said in a release.
The 16-year-old student who brought the BB gun to school had been keeping it in his backpack; police said he brought the BB gun to school so he could take it to a friend's house afterward.
In homeroom Thursday morning, other students saw the BB gun in the student's backpack and told him to shoot it at another student, after which the student fired a single pellet at his classmate, police said. Police didn't specify whether a teacher had been present in the room at the time or whether the school went into lockdown.
