An otherwise routine evening at Rolling Meadows High School turned tense on Wednesday when an 18-year-old student was taken into custody after police say he threatened classmates with a knife on campus. Officers detained the student at about 7:20 p.m., recovered two knives, and reported that no students or staff were injured.

According to NBC Chicago, officers were called to the school after reports that a student had threatened others with a knife. When police arrived, they detained the student and seized two knives. Authorities told the outlet the incident is being treated as an isolated one and confirmed that no one was hurt.

Police response and school operations

Local reporting indicates the student is 18 and that, after he was taken into custody, school activities on campus were allowed to continue. Patch reports that investigators are working with Township High School District 214 as they continue to look into the incident.

Recent safety scares in the area

This is not the first safety scare connected to the Rolling Meadows campus in recent months. In October, a student found a live bullet inside the building, which led to an early dismissal and canceled after-school activities, as reported by the Daily Herald. Last September, police confiscated a gun at nearby Plum Grove Middle School, again without any injuries, according to CBS Chicago.

Investigation ongoing

Police say the investigation into Wednesday's reported threat is ongoing and have not released additional details about the student's identity or any potential charges. Authorities are asking anyone with information to contact the Rolling Meadows Police Department, according to Patch.
