Philadelphia police say an eighth-grader attacked his science teacher during class and has been arrested.
Officer Jillian Russell says the 14-year-old was taken into custody on Monday at Leeds Middle School in Mount Airy.
School district spokesman Fernando Gallard (geye-YAHRD') says an argument broke out as the 60-year-old teacher returned an assignment to the teen. He says the confrontation escalated, and the eighth-grader began punching the teacher repeatedly.
Gallard says the teacher was treated at a hospital and released. The teacher isn't expected to immediately return to the classroom.
Gallard says state law requires the student to be charged with aggravated assault. Russell couldn't immediately confirm the charges.
