Nassau police say they have arrested a student at Elmont High School after a switchblade was found in his backpack.

Detectives say they responded to the school at 555 Ridge Road on Tuesday afternoon after they received a 911 call. The 18-year-old was detained by school staff and was placed into police custody upon their arrival.

Police say Dayvion Campbell, from Elmont, is charged with criminal possession of a weapon and was released on an appearance ticket to return to the youth section of the First District Court in Hempstead at a later date.

With incidents like this on the rise recently, we spoke with a child psychiatrist. He says a child bringing a weapon to school requires serious intervention, including counseling.

"Limit their inappropriate aggression, teach them more prosocial behavior, and recognize when it's safe to have them in certain environments," says Dr. Victor Fornari, a child and adolescent psychiatrist.

We've reached out to the Elmont School District last night and again this morning for comment and are waiting to hear back.
