NILES, MI- No one was injured when the Niles Fire Department responded to a grease fire at a Kentucky Fried Chicken. Workers first noticed a fire underneath the fryer, but then the flames spread upward. As some employees called 911 and evacuated the restaurant, other workers used a portable fire extinguisher to put out the flames. When the fire department arrived, the flames had been extinguished and damage had been limited to the frying machine.
