BOLINGBROOK, Ill. - A 14-year-old high school student at Bolingbrook High School in Illinois faces aggravated assault charges after he allegedly threatened a teacher with a BB gun, reports CBS Chicago.
Bolingbrook Police Sgt. Mike Rompa said the student “threatened harm” because of a grade the teacher had given him, according to the station.
After making the threat, the student reportedly retreated to a washroom, where police found him.
Rompa said the school was placed on lockdown around 8:30 a.m. Thursday but the lockdown was lifted within minutes after determining that the student acted alone.
Valley View Unit District 365U Supt. James Mitchem said in a statement that the incident was over in six minutes “due to the swift reaction of our security team, staff and students.”
Mitchem said no one was hurt and “every precaution was taken.”
Sgt. Rompa said the teen was transported to the River Valley Youth Detention Facility for processing and medical evaluation.
