MILTON (CBS) – A Milton mother is furious that her 13-year-old son was suspended for accidentally bringing a two-inch folding pocket knife to school.

Ife Oshun says her eighth-grader is a Boy Scout who has been certified to use his knife as a tool. She said he left it by mistake in his backpack one day but never took it out at the Pierce Middle School.

She says the boy showed friends while walking home off school property. One of those friends told his parents who Oshun said “freaked out.”

The boy was suspended for eight days for possessing a weapon on school property after he admitted the mistake.
