Officials at Percy Julian Middle School in the Village of Oak Park said more than a dozen catalytic converters were stolen from school buses, causing transportation delays throughout Monday.
According to the school, its transportation service, Lakeview Bus Line, suffered an overnight break-in that led to the thefts.
In a letter to parents, school principal Jeremy Christian said buses are expected to run on schedule in future, although services may include different buses and drivers than usual.
“We appreciate your patience and understanding as Lakeview works to recover from this unfortunate situation,” the letter read.
Services are expected to resume normal operations next week, according to the school. The letter adds that parents with questions or concerns can contact Lakeview Bus Lines at (708) 234-5555.
