METHUEN, Mass. — A 10-year-old boy has been arrested after police say he shot a BB gun at two school buses full of children in Massachusetts.

Police say both buses had about 63 students aboard in grades K-8 when they were shot at Wednesday. The Boston Herald reports the buses were leaving Marsh Grammar School in Methuen.

The impact of the pellets shattered multiple bus windows. No injuries were reported.

Investigators traced the pellets to a boy who police say fired them from his home. Authorities say the child is not a student of the district’s public schools. His name has not been released.

The boy is facing several charges, including malicious damage and one count of assault with a dangerous weapon for every student on board the bus.
