CHICAGO (CBS) — A west suburban high school student who made a threat toward another student on social media is facing several weapon charges.

An investigation began Monday after Hinsdale South student came forward with information about social media postings. A male student posted on Snapchat threatening another student, CBS 2’s Sandra Torres reports.

Officers searched the student’s home, as part of the investigation, and found several guns, ammunition, paper shooting targets, explosives, knives, brass knuckles and gas masks, prosecutors said.

The male student has been charged with one count of possession of an explosive or incendiary device, two counts of unlawful use of a weapon, three counts of possession of firearms without an FOID card, and two counts of disorderly conduct, all felonies.

Police cannot release the identity of the 16-year-old student since he is a juvenile.

Judge Michael Wolfe ordered the teen be held after a detention hearing Wednesday morning, prosecutors said. He is next scheduled to appear in court Oct. 19.

“We take any threat to the safety and security of our students and teachers very seriously,” State’s Attorney Robert Berlin said in the statement. “Students and teachers alike must not fear for their safety at school. With fear in our classrooms, teachers can’t teach and students can’t learn,” he said.

District 86 Superintendent Bruce Law said the district alerted parents on Tuesday.

“It’s very disturbing and a constant reminder of the challenges we face in the schools to keep students safe,” Law said.

CBS 2’s Roseanne Tellez received reaction for parents and students. The school offered to provide support in any way they can, according to school officials.

Police continue to investigate. They insist this case shows the importance of the saying, ‘if you see something, say something.’

“First and foremost, I want to thank the young man who came forward and brought these alleged threats to our attention. Sometimes it can take a tremendous amount of courage to do the right thing,” Berlin said.
