READING, Pa. -

Reading police have been called in to investigate a case of a student who took a knife to school.

The seventh grader took the knife to Northeast Middle School on Wednesday and, at the end of the day, gave it to a female classmate to hold, district officials said.

The girl's mother found the knife and turned it over to the school on Thursday, officials said.

School officials identified the student who gave the knife to the girl. He told them he had the knife "for protection" outside of school and had no intention of using it inside the school.
