Scotland’s wild creatures are a national treasure, but there is a hard core of criminals who want to exploit our wildlife for financial gain or harm it in the name of sport. This four-part series looks at the work of the Wildlife Detectives who protect our precious animals, plants and birds. In this first episode it’s Spring and police are hunting down a gang responsible for causing dogs and badgers terrible suffering, tracking down a rare bird in a back garden in Perthshire and protecting sea eagles on Mull.
