North Aurora Middle School Student, 12, Arrested For Bringing Grenade To School

A 12-year-old suburban Chicago middle school student faces a charge of disorderly conduct after he was caught with a hand grenade at school Tuesday.

The boy brought the grenade to Jewel Middle School, 1501 Waterford Road in North Aurora, Ill., the Kane County Chronicle reports.

After a schoolmate told staff that the student had a bomb in his book bag, North Aurora Police and, ultimately, the Kane County Bomb Unit became involved. They found the grenade in the boy's bag and determined that it had been deactivated because its center was hollowed out, according to the Chronicle.

As Patch reports, no one was injured in the incident and the school was not evacuated or put on lockdown.

Mike Chapin, West Aurora School District spokesman, told the Aurora Beacon-News that the boy will face "pretty strong" discipline on top of his disorderly conduct charge. After he was initially taken to the North Aurora Police Department, he was referred to Juvenile Court Services.

Earlier in the week, a middle school student in northwest suburban Island Lake, Ill., brought a loaded handgun to school, causing the school to go on a three-hour lockdown. No one was hurt in that incident.
