WOBURN - Parents and students at a Woburn middle school were stunned by an outburst of pre-teen violence after a sixthgrader was accused of slashing a classmate with a steak knife in the school auditorium early Thursday. "I'm really scared," said Lucas Almeida, a sixth-grader at the John F. Kennedy Middle School in Woburn, one of several students who spoke outside the school with their parents present. "It was really crazy, I was never expecting this to happen to this school," Almeida said. Just before 8 a.m.

Thursday, an 11-year-old sixth-grade boy stabbed a 12-year-old classmate in the school auditorium with a steak knife as a fight escalated, according to city officials and students.

"I had just gotten in the school and I saw two boys fighting on the side," said eighth-grader Julia Baker.

"I got really nervous, I didn't know what happened, stuff like this usually doesn't happen. I was really scared."

The 12-year-old was transported to a local hospital, according to authorities, with "superficial injuries that are not considered life-threatening."

The school was placed in a brief lockdown as staff and school police responded.

"The alleged assailant, an 11-year-old male student, was quickly identified and placed in custody and a small knife was seized," Woburn Mayor Scott Galvin, Police Chief Robert Rufo and Superintendent of Schools Matthew Crowley said in a joint statement.
