CHARLOTTE, N.C. -- A Charlotte-Mecklenburg Schools bus caught fire in southwest Charlotte Tuesday afternoon.

Charlotte Fire responded to a call on Westinghouse Boulevard near Downs Road.

The CMS bus was not carrying children at the time of the fire, firefighters say. Medic says no one was transported.

Charlotte Fire Investigator David Williams said the fire may have originated from the engine compartment.

"[The fire] Spread into the driver's compartment and the passenger compartment of the bus," Williams said. "Right now, it remains under investigation until we have all representatives together."

This isn't the first time a school bus caught fire in the Charlotte area during the 2017-2018 school year. On October 19, 16 students were evacuated after a Charlotte-Mecklenburg Schools bus caught fire in east Charlotte.

Morris Dillinger was working near the site of the fire. He said the fire was really hot from where he was at.

"I tried to stay away from the smoke because the smoke was so gassy with the fiberglass in the paint and the rubber in the fuel burning altogether," Dillinger said. "It was tough on your lungs."

Following the incident, CMS released the following statement:

Charlotte-Mecklenburg Schools transportation leaders are investigating a school bus fire this afternoon, Tuesday, November 14. No students were on board bus # 188... The driver reported smelling smoke, stopped the school bus immediately and exited before the bus ignited. The driver was not injured.
