BOSTON (CBS) – A 16-year-old student was arrested Monday morning at the Jeremiah E. Burke High School for having a hand gun.

The fire arm was not loaded, but the student was in possession of a small amount of ammunition, the school said in a statement.

School administrators contacted local police to handle the issue, they said.

The school day was not interrupted.

?These types of incidents are rare in our schools and that only makes today more frightening and disappointing,? said Superintendent Carol R. Johnson. ?The Burke is a great high school, and we will work closely with the Boston Police and our own school police to ensure it remains a safe and welcoming learning environment for all students and staff. This type of conduct will not be tolerated.?
