A 17-year-old Jewish high school student from Jerusalem was arrested on Wednesday night after he threatened a teacher with a knife.
The incident happened on Wednesday, when the teacher broke up a fight between the student and another teacher.
The student then held the knife up to the teacher's throat and threatened to kill him.
The student fled the scene with the knife and the teacher was not harmed. Police investigators arrested the student last night and he was brought for a remand hearing on Thursday morning in the Jerusalem Magistrates Court.
