Joar Hesten's mission to save a whale rumoured to have escaped from the Russian navy. Norwegian Joar Hesten was fishing for cod in the Arctic when he came across a beluga whale wearing a harness. He helped to free the animal, but when he took a closer look at the harness he saw that it was labelled ‘Equipment of St Petersburg’. Theories started swirling that this whale had once belonged to the Russian military, and it was nicknamed Hvaldimir, the 'Russian spy whale'. As Hvaldimir's fame grew, Joar became determined to protect him from human contact. Presenter: Emily Webb Producer: Saskia Edwards Photo: Joar with Hvaldimir Credit: Aleksander Nordahl, DN/D2
