Pittsburgh school officials said a student brought two knives and a metal stake to class.
Letters were sent home to Mifflin School parents on Tuesday about the alleged incident.
“That’s very alarming,” said a parent.
Parents showed reporter Courtney Brennan three letters that have been sent home this school year about concerning incidents.
One detailed Tuesday’s incident. The second letter was about an alleged bomb threat in October, and a third letter said a student allegedly brought a pellet gun to school in November.
A source told Brennan the Mifflin student involved in Tuesday’s incident is a second-grader and brought the knives to school because he was being bullied.
Police are investigating.
With the recent focus on the violence at Franklin Regional High School, students worry it will happen in their hallways.
