SPRINGFIELD -- Springfield firefighters extinguished a fire in the ductwork of a Burger King restaurant at 400 Cooley St. Wednesday afternoon after witnesses reported seeing flames shooting from the roof.

Dennis Leger, aide to Fire Commissioner Bernard Calvi, said firefighters found the exhaust vent ductwork for a grill ventilation system had caught fire and it was quickly extinguished. The flames were contained by the ductwork and there was no structural damage to the building.

Leger said the city's Health Department was called in to investigate and the fast food restaurant will remain closed at least until Thursday.
