After a Northern Ireland soccer match between Ballymena United and Distillery on Saturday, someone threw a lamb's leg onto the field. According to the USPCA, the act "demonstrated general disregard for animal welfare." From the BBC News:
"It also follows a recent incident in which a horse's head was left outside the home of a hockey player in Cookstown," (the animal welfare organization's spokesman) added.
