HINGHAM, Mass. (AP) — A 13-year-old boy who was spotted behind a Hingham elementary school with a pellet gun, prompting a brief lockdown, is facing a number of charges, authorities say.

The teen will be charged with assault with a dangerous weapon, carrying a dangerous weapon on school grounds, being a minor in possession of a BB gun and disorderly conduct, Sgt. Steven Dearth told the Patriot Ledger (http://bit.ly/1akFGLP ).

Foster Elementary School went into lockdown for about 20 minutes Thursday after school officials received a report of someone in the woods behind the school, possibly carrying a gun and wearing a ski mask.

Although school was over for the day, some students and staff involved in after-school activities remained in the building.

Police who were investigating found the boy and recovered an Airsoft gun, which shoot plastic pellets.

Police decided to pursue charges against the teen after interviewing witnesses, Dearth said.

The teen was released to the custody of his parents. His name was not released because of his age.
