A 10-year-old boy who dispensed pepper spray Wednesday in a hallway, closing a Uniondale elementary school for two hours, has been charged with unlawful possession of noxious material, police said.
The boy was released to a family member and will appear in Family Court on Nov. 4, Nassau police said.
Twenty students -- including the boy -- and four faculty members were taken to a hospital for eye and throat irritation after the spraying at Northern Parkway School at 11:10 a.m., police said.
Police are investigating how the boy obtained the irritant, a department spokesman said Thursday.
The school was evacuated as police, a hazardous materials unit, and fire departments from Uniondale, West Hempstead, Roosevelt and East Meadow responded to the scene.
The school defines "pepper spray or other noxious spray" as a weapon, per federal law. The school's conduct code says such a spray should be confiscated, with the student's parents being notified and "appropriate disciplinary sanction if warranted," including possible referral for prosecution.
