No one was injured Thursday by a fire that damaged a house at 1338 Derby Lane on the city’s east side. A large concentration of fire was visible toward the back of the two-story structure as firefighters arrived on the scene. The blaze was brought under control in less than 15 minutes, but the home is uninhabitable. Damage is estimated at $50,000. The American Red Cross of Northwest Illinois is helping the displaced family with housing. The cause of the fire is under investigation.
