Investigators say last week's fire at Scott Elementary School in Naperville was arson and the school is implementing new safety procedures.
According to a notification sent to parents tonight, Scott School officials say both the Naperville Police and Fire Departments have determined the fire was deliberately set in a boy's bathroom.
The fire started at about 9:53 a.m. on Friday, Nov. 20, and caused about $100,000 in smoke damage at the school. Everyone was evacuated safely.
The investigation is being called "active" and no one has been charged yet.
