Two students were arrested for bringing knives to Fitchburg High School on Monday morning.
Fitchburg police said they received a call around 9:30 a.m. from staff at the school saying that a threat might have been made to the school. The threat reportedly involved the possibility that a weapon had been brought to the school by a 17-year-old male student.
School administrators placed the building into lockdown as a precaution as they searched the building for the student in question.
The student was located a short time later in the library and arrested for carrying a pocket knife on school grounds. Another student who was with him at the time, a 16-year-old male, was also arrested for carrying a kitchen knife on school grounds.
