Grease in the duct work of a restaurant apparently caused a smoky fire that led to the evacuation of Westfield Wheaton Mall Saturday.
The fire, in the duct work of a Crisp and Juicy restaurant, caused about $180,000 in damage, Montgomery County fire officials said.
One firefighter suffered a minor injury.
The incident occurred around 11:15 a.m. Fire officials cleared the building of customers and workers as they put out the fire.
Heavy smoke kept people out of the mall for hours. It reopened around 2:30 p.m.
