A student was stabbed at a high school in Malden, Massachusetts, after a fight broke out Thursday afternoon.

Malden High Principal Chris Mastrangelo said, "A student's forehead was hit with a sharp object. The injuries were not life threatening."

The injured student, however, was taken away by ambulance.
Police did take the other student -- a minor -- into custody and are investigating the incident.
"We are talking to some students who might have been present and can help us and give us some enlightenment on what happened," said Malden Police Chief Kevin Molis, adding he has no concern this could be an ongoing type of thing such as gang violence.
Police are trying to clear up what type of weapon was used in Thursday's incident.
When asked if it was a knife, the police chief responded, "All we're hearing is a sharp object. Again, it would be speculation as to how the mechanism of injury occurred and what was involved. We're piecing things together as we speak."
Video of the attack is shocking. Appearing in a hallway, two boys can be seen fighting, with one trying to stab the other, jabbing at him twice. The victim did not appear badly hurt, fighting off his attacker who runs away.
The school was locked down during the incident around noon, but that has since been lifted.
