Police were called to Riverhead High School on Thursday after a student was found to be in possession of a knife, school officials confirmed Thursday afternoon.
The knife was found in the student’s backpack, said Superintendent Nancy Carney.
The student was a recent transfer to the district, she said.
Ms. Carney said the student in question will be receiving an automatic five-day suspension, pending any additional disciplinary action.
“Obviously, anything involving a weapon we take very seriously,” she said.
Riverhead police said the incident is under investigation.
