SINKING SPRING, Pa. (AP) — Officials at a middle school in eastern Pennsylvania say they have expelled a 14-year-old student who admitted in juvenile court to stabbing a classmate in school.

The Reading Eagle reports the Wilson Southern Middle School eighth-grader admitted at a hearing last week to stabbing the other student three times with a pocketknife. School board members approved the expulsion Monday.

The victim is recovering after being treated at a hospital. The stabbing happened in a second-floor hallway at the school on the morning of Jan. 15.

Police have said that a dispute on a social media site may have precipitated the altercation.
