Brazil now has police buffaloes ... Is Bob Marley turning in his grave?
The buffalo can go into action with vehicles and are regularly called out on duty with the fire service. They are always ready to trot off to help douse a blaze in some thatched hut or drag a car out of the Amazonian mud.
Their horns, which have a span of a metre and a half, hang down impressively for all the world like the drop handlebars of a giant's bicycle.
