A middle school student in Seabrook has been criminally charged for making threats to "shoot up" his school.
The students' peers first reported the threats on Friday. On Monday, SAU 21 Superintendent Bill Lupini says that students returned with more detailed and serious reports.
School officials say they do not believe the school was in danger, but the student is not attending classes.
Police say the students' name and many details - including plans for returning to school - cannot be released because of juvenile privacy rules.
