COLORADO SPRINGS, Colo. -- An 11-year-old boy has been arrested, accused of stabbing a student in a middle school hallway, the Colorado Springs Gazette reported.
The boy, who was not identified because of his age, was charged with second-degree assault after the incident on Oct. 7 at Carmel Middle School, the Colorado Springs Police Department said.
The victim, also 11, was stabbed with a pencil and suffered a punctured lung that required trauma surgery and a temporary breathing tube, police said.
The boy, who was arrested Monday, has been suspended from school, Harrison School District 2 said.
The school came under fire for not calling an ambulance for the student. Superintendent Andre Spencer said last month that a health technician assessed the student and determined he was not in "imminent danger."
The victim's parents were called and they took him to a local hospital. The victim then was was taken to Children's Hospital Colorado in Aurora for emergency surgery.
The district said the students were going between classes when the incident happened.
Spencer told the newspaper last month the stabbing was part of "an unfortunate, isolated situation between these two students."
