Fire officials say two people were injured during a fire at an apartment building in Fond du Lac Wednesday. According to the Fond du Lac Fire Department, crews were called to the Countryside West Apartments at 869 Security Drive around 6 p.m. The complex houses 24 units. When crews arrived, they found smoke coming from a second floor apartment, with tenants evacuating while fire alarms were going off. Officials say two residents who occupied the apartment where the fire happened suffered smoke inhalation. They were then taken to an area hospital for evaluation after being treated by paramedics. No other injuries were reported. Fond du Lac Fire Chief Peter O’Leary says the fire was caused by a flare up of grease while tenants were cooking.
