SIOUX CITY, Iowa (AP) — A California-based developer of a 12-story historic art deco building in downtown Sioux City has filed for bankruptcy protection, indefinitely delaying an effort by an eastern Iowa bank to foreclose on it.

Cedar Rapids Bank and Trust filed for foreclosure on the Badgerow Building in April.
