A bus driver has been fired and a bus monitor has been put on paid administrative leave after a young special needs student was left alone on a school bus for four hours Tuesday.

The four-year-old boy was checked out by EMTs once he was found and is uninjured. His family told WBZ-TV he is autistic and nonverbal.

According to the Revere Public Schools Superintendent Dianne Kelly, the bus monitor is an employee of Revere Public Schools. The bus driver was hired through an outside contractor, VSP Livery Service.

The bus company has since confirmed the driver was fired and that this has never happened in their 20 years of business.
