Police in Hillside are investigating an unfounded weapons incident that locked down the high school Tuesday.
Hillside Police officials told RLS Media that they received a piece of information from the school resource officer at the high school that a student had reportedly brought a firearm to the building.
According to Hillside Police Chief Vincent Ricciardi, officers responded immediately, and the school was locked down as a precaution while cops investigated the situation.
Chief Ricciardi said ultimately, the complaint was determined to be unfounded and classes resumed.
It is not clear what the resource officer observed or overhead to come to the conclusion that a weapon was in the school building.
The incident remains under investigation.
