An animal rights group is boasting about its vandalism at the Iowa State Fair early Sunday.
Sergeant Scott Bright of the Iowa State Patrol says a group called Iowans for Animal Liberation has admitted to vandalizing the butter cow with red spray paint.
Vandals also spray-paintied the words "freedom for all" on the display case glass.
Authorities say the vandals apparently hid in the Ag Building, waiting until it closed, then snuck into the butter cow display case.
The damage was cleaned-up quickly and butter sculptor Sara Pratt was able to do some touch-up work before fair-goers arrived.
