A 16-year-old boy was arrested and is facing multiple charges after a stabbing at Methuen High School on Monday resulting in a school lock down.
Methuen police said an investigation indicates a 15-year-old former student at the school entered the building at about 11:40 a.m. and confronted a 16-year-old student.
"The incident escalated to a physical confrontation, subsequently resulting in the 16-year-old student stabbing the former student," said Methuen Police Chief Scott McNamara.
The 16-year-old suspect then chased after another student while still brandishing a four-inch knife, police said. A staff member and another student tackled the suspect, police said.
The 16-year-old faces two counts of assault and battery with a dangerous weapon, a knife; one count of armed assault with intent to murder; one count of carrying a dangerous weapon on school grounds; and one count of assault by means of a dangerous weapon.
The 15-year-old has non-life-threatening injuries and is in stable condition at Boston Children's Hospital, police said. He will likely be charged in connection with unauthorized entry into the school, police said.
“At this time, this does not appear to be a random incident and we are fully cooperating with Methuen Police as they conduct a full investigation,” Methuen Public Schools Superintendent Brandi Kwong said in a statement. “We believe that there is no further threat to students, staff and the community at large.”
