Fire officials say a family was uninjured but displaced after a fire engulfed the attic of their home in Mundelein Saturday evening.

The Mundelein Fire Department responded around 5:23 p.m. Saturday to the 500 block of Bonniebrook Avenue for a report of a structure fire.

Mundelein Deputy Fire Chief Jeremy Lockwood said crews received a report of a fully involved attic fire in a home.

Firefighters arrived on the scene within five minutes and found heavy smoke showing from the attic.

Lockwood said the family and their cat had evacuated the residence prior to the fire department arriving on the scene.

Firefighters pulled a hose line to the front of the home and aggressively attacked the fire while other firefighters connected to a nearby fire hydrant, Lockwood said.

The second arriving fire crew pulled a second hose line and entered the structure to check for extension of the fire.

The incident was fought by 22 firefighters staffing five fire engines, one squad, three ambulances and one incident command vehicle.
