Minot Forest Elementary was evacuated Friday afternoon after a training grenade was found in a child's backpack, Wareham Fire Captain Bruce Kelenosy confirmed.

The device was found to be inert by emergency responders.

The incident was reported around 1:30 p.m. after a student showed a "suspicious object" to her teacher, Wareham Public Schools Superintendent Barry Rabinovitch said. The teacher informed Principal Joan Seamans, who evacuated the building.

Students were allowed to board buses at approximately 3 p.m. after Wareham Fire Chief Robert McDuffy declared the area safe, Rabinovitch said. The entrance of the school was closed to vehicles, except for "special needs" buses, however, so larger buses lined up on Minot Avenue, causing brief traffic delays. Students picked up by parents were bused to Hammond Elementary in Onset.

"The principal will be taking appropriate disciplinary measures after taking all circumstances into account," Rabinovitch said.

Parents were notified via the district's phone alert system regarding when to pick up items the students left in the building, such as Halloween costumes.
