Police said they responded to Oak Park and River Forest High School around 12:30 p.m. Tuesday after receiving a report that 18-year-old Keyon Robinson intended to bring a gun to the school that day.
The teen was stopped on school grounds before entering the building, where police said they recovered a loaded handgun.
Robinson was then taken into custody, Oak Park police said.
The handgun recovered was later identified as a self-manufactured unmarked semi-automatic firearm, also known as a ghost gun, according to the Cook County State’s Attorney Office.
Robinson has been charged with two counts of aggravated unlawful use of a weapon. He was also found to have an active warrant out of DuPage County for a traffic violation, according to police.
He is being held on a $500,000 bond.
