LORANGER - A 17-year-old was arrested Thursday for bringing a gun onto Loranger High School property. 

The Tangipahoa Parish Sheriff's Office said deputies got a tip around 8:30 a.m. that a Loranger High student had a gun in their car. Loranger High, Middle and Elementary went on lockdown until a weapon was found around 10 a.m. Deputies said the gun was in the trunk of 17-year-old Denim Lusk's vehicle.

Lusk was arrested and booked with possession of a firearm on school property and illegal disruption of school operation. 

The school's superintendent, Melissa Stilley, issued a statement commending the school administration and law enforcement partners for handling the situation "perfectly" and said everyone worked together swiftly in less than 30 minutes after the tip. She confirmed a student was arrested and said state law required a two-year expulsion for students who have a weapon on a school campus.
