Bel Aire police say some residents were evacuated for several hours and others told to stay indoors after a grenade was discovered at a home damaged last week by a fire.

Police Chief Darrell Atteberry says a construction crew was tearing into the home’s ceiling Thursday when the grenade dropped from the attic. The crew backed out as a precaution and notified the homeowner, who called 911.

Atteberry says the current owner had only lived in the home for about 11 months and was unaware the grenade was in the attic. Wichita police sent its bomb squad to the scene to check for additional devices and safely removed the grenade.
