A mysterious beluga whale was dubbed a spy when he appeared off Norway's coast wearing a Russian harness. Two years on, little more is known of the animal's past, but now activists are concerned for his future welfare.
One campaign group led by an American filmmaker wants to create a sanctuary and is urging Norway to support it.
The whale's first known sighting in Norway came at the end of April 2019, when a blob of white flashed past fishermen near the islands of Ingoya and Rolvsoya.
