A Kennedy Middle School student gave a note to a teacher Friday morning that said “bombs” were set to go off in the school, according to Waltham police.
After an investigation, police determined that the 15-year-old student wrote the note. The student then admitted that the threat was false and that there were no bombs in the school, police said.
Students and staff were evacuated to Waltham High School when the threat came in.
The Massachusetts State Police Bomb Squad cleared the school, at 655 Lexington St., with bomb-sniffing K-9s, and the school was deemed safe at about 11 a.m.
The student was charged with disturbance of a school assembly and a false report of a weapon or property capable of causing damage.
