HELLERTOWN, Pa.—A high school student in eastern Pennsylvania is in trouble with the law after an alleged assault of a principal.

Police said the Saucon Valley High School principal shielded himself with a stool as a female student threw knives, rolling pins, ceramic bowls, broken glass and a wooden stool at him. Police said the 17-year-old student also punched and kicked the principal.

Neither the teen nor the principal in the Feb. 24 incident were identified by authorities.

The teen was charged with aggravated assault, reckless endangerment, harassment, disorderly conduct, criminal mischief and related counts.

It was not immediately clear if the principal was injured. The Saucon Valley School District did not immediately return messages for comment.
