Salamanca High School was placed in lockdown around 9-this morning when a student threatened a teacher.
A 15-year-old student picked up a pair of scissors and broken lacrosse stick making the threats.
"The student did make some overt verbal and physical threats about causing injury to self and others," said Salamanca Schools Superintendent Robert Breidenstein.
Staffers tried to intervene and negotiate with the student and Salamanca Police were called in.
