STOCKTON (CBS13) — A Stockton student who was already under suspension for allegedly threatening school staff has been arrested on suspicion of bringing a knife to campus, authorities say.

On Wednesday, the Stockton Unified School District Police Officer’s Association says an officer spotted a student at Stagg High School who was not supposed to be on campus due to him being suspended.

Officers detained the student and escorted him off campus. They then did a pat search and soon discovered he had a large hunting knife in his waistband.

The student was immediately arrested and taken to juvenile hall. He’s facing charges of bringing a weapon on campus.
