17-year-old student stabbed by a 15-year-old teen in the neck, back, and stomach outside Uniondale High School in Nassau, Long Island

Two teens got into a fight outside Uniondale High School during dismissal around 2:45 p.m., which escalated when one pulled a knife.

A 17-year-old student was stabbed repeatedly by a younger teen outside a Long Island high school Monday afternoon, police said.

The teens got into a fight outside Uniondale High School during dismissal time around 2:45 p.m. and escalated when one pulled a knife, according to Nassau police.

The alleged attacker, 15, stabbed the other teen in the neck, back, and stomach, police said. The teen, a student at Uniondale, was taken to Nassau University Medical Center in stable condition.

The 15-year-old fled on a bicycle as school security guards gave chase. However, he was apprehended by police a short time later. The young assailant is not a Uniondale student, Pix11 reported Monday night.

The teenage suspect has not been publicly identified by police, as he is a minor.

Nassau police are investigating the stabbing and how the alleged attacker entered the Uniondale campus.

Uniondale Schools Superintendent Dr. Monique Darrisaw-Akil, Ph.D., notified the parents of the school about the stabbing.

The Uniondale School District has a zero tolerance policy for instances of violent or aggressive behavior of any kind,” Darrisaw-Akil said in the statement to parents. “The District is cooperating with law enforcement in their investigation.”

He added that counselors will be available on campus for students on Tuesday.

Rest assured that the welfare of our students is our number one priority. We are actively working to review our security measures and protocols,” Darrisaw-Akil said.

In October, another student was stabbed outside a New York school, the Manhattan Science and Math Center in the Bronx, just after he was questioned by one of the suspects about his gang. Another gang-related stabbing involving a teenager happened in October at a Staten Island ferry terminal.
