NORMAL (AP) — A 14-year-old boy faces 16 felony charges after authorities accused him of firing gunshots into the ceiling at a central Illinois high school before a teacher tackled him.

A public defender entered a not guilty plea for the boy during a juvenile court hearing on Monday. WJBC reports the boy is charged with multiple counts of unlawful restraint and unlawful use of a weapon. Earlier Monday, Normal police said the boy had three handguns and ammunition with him during the Friday incident at Normal Community High School.

The boy also reportedly had a hatchet and two knives. No one was injured.
