“Earlier this summer, the Hull Police Department held an active-shooter drill on the eighth-grade floor at Memorial Middle School. The department periodically conducts these drills to maintain readiness in the event of an emergency.

“On Wednesday, Aug. 30, a person servicing the copier discovered a training round nearby. Please note that these training rounds do not have the capability to leave the barrel and become a projectile. This resulted in a short lockdown of the school out of an abundance of caution for our students and staff. When officers responded to the school, they immediately identified that it was a training round, and the lockdown was ended.

“On Thursday, Aug. 31, a teacher found several more training rounds inside a plastic cup. We did not call for a lockdown at this point because we recognized the items. The school resource officer and the lead police instructor for the active shooter training event conducted a protective sweep of the school on Thursday afternoon to make sure no other items related to the drill were left behind.

“The Hull Police Department and the Hull Public Schools would like to apologize to parents and students for any alarm this caused.

“We also want to stress that at no point were any students, teachers or school personnel in danger.

“These drills are important to make sure everyone in our schools is safe in the event of an emergency. The school department and police will meet in the coming days to make sure any future drills address these concerns.”
