Tinley Park police said Friday that a 13-year-old boy has been charged with aggravated disorderly conduct after making online threats against students at Grissom Middle School in the village.
The boy was charged on Thursday and police said the threat was made on September 14.
The youth is not a student at Grissom but had gained unauthorized access to a Grissom student’s social media account and similar, and had used it to make the threats appear to be from the student whose identity he stole, police said in a news release . drop.
Tinley Park police initially said they were working with the Cook County Prosecutor’s Office and said a person suspected of making the threats is a juvenile, limiting what information they can release.
Police were stationed at the school, 17000 S. 80th Ave., from Sept. 17 to Sept. 20.
Grissom is part of Kirby District 140 and, according to Superintendent Dan Callaghan, families were notified over the weekend of Sept. 14 and 15, informing them that police were investigating a social media post involving a potential threat against Grissom.
Callaghan said the district had been informed by police at the time that a juvenile suspect had been identified and that police had “reviewed the situation and assured us there was no ongoing threat to the safety of our students or staff.”
Police said several people had seen the threat online and reported it to police.
In addition to the Tinley Park incident, threats have been investigated in recent weeks involving schools in Elgin, Glendale Heights, Richton Park, Olympia Fields, Hinsdale, Park Forest and Chicago Public Schools, among others.
