BALTIMORE — Police say a 12-year-old middle-schooler threatened a classmate with a folding knife during a fight on the school bus.

Baltimore police spokesman Cpl. Shawn Vinson tells The Baltimore Sun the Dumbarton Middle School student was charged as a juvenile with assault with a deadly weapon. The student was also found to have a can of pepper spray during the Monday incident.

The other student involved in the fight, a 13-year-old, has been charged with assault.

It’s unknown if either student has a lawyer.

Vinson says no one was injured during the fight.

An assistant principal, Cheryl Scott, said in a voicemail to parents that another student had a folding knife on the same bus in an unrelated incident.

Baltimore County Public Schools didn’t respond to the newspaper’s request for comment.
