A 16-year-old Fort Lee High School student is facing charges related to a stabbing that left a classmate critically injured, according to the Bergen County Prosecutor’s Office.

Police say they responded to Fort Lee High School on Lemoine Avenue shortly before 11 a.m. for reports that a male student had been stabbed multiple times. The school was on lockdown for the rest of the day.

Students had to exit the building by grade, as some parents rushed to the school after getting calls and texts from their teenagers.

"It was complete chaos," said Angel Serrano-Lugo, who told News 12 that he's friends with the victim and saw him after the stabbing occurred. "He said, ‘He stabbed me, he stabbed me. Please help me please help me.’”

Serrano-Lugo says the stabbing occurred in the school bathroom.

"Girls were crying, everyone was trying to help my friend and then security came, picked him up and we all had to go to different rooms," said Serrano-Lugo.

He says he immediately texted his mom, Doris Lugo, about the lockdown.

"There was another call saying that police activity is being present at the school, not to show up. But of course, I had to show up ‘cause my kid is there,” Lugo says. "I’m really surprised at such a prestigious school like this for an incident like this to happen," she said.

The prosecutor’s office says that the attack stemmed from an altercation between the suspect and the victim in the school bathroom. They say the victim was stabbed in the neck, abdomen, back and arm. The victim is said to be in critical but stable condition.

Officials say the 16-year-old suspect was placed in protective custody and charged with juvenile delinquency, "specifically: first-degree attempted murder...second-degree aggravated assault" and other charges. He is being held at the Bergen County Juvenile Detention Center pending a hearing.

Parents say the school doesn't have metal detectors and maybe this could have been avoided if they did.

Candace Bell, whose daughter is a student, said, "Crime doesn't discriminate, so I'm totally for having metal detectors now."

The lockdown was lifted around 2:45 p.m.
