WEST UNION, Iowa (AP) — Some livestock producers in northeast Iowa are considering extra security measures in the wake of vandalism at three hog operations last weekend.

Fayette County Sheriff Marty Fisher told the Waterloo-Cedar Falls Courier that farmers are looking at additional lights and other measures.

Vandals broke into hog confinements near Sumner and West Union late Saturday and early Sunday and caused thousands of dollars in damage. Several hogs were released at two sites.

Fisher says the items taken were small, if anything, and a motive hasn't been determined.
