Yet another case of violence at an area high school – this time at Guilderland High.
Police arrested student Mark Balthazar of Slingerlands Thursday. Police say he had an argument with a group of students and pulled out a knife threatening them.
Nobody was hurt.
Balthazar was charged with criminal possession of a weapon and menacing. He was arraigned in Guilderland Town Court and released.
The incident comes less than a week after a student was stabbed at Albany High.
