A white beluga whale named "Hvaldimir," first spotted in Norway not far from Russian waters with a harness that ignited rumors he may be a Moscow spy, has been found dead.

The 4.2-meter (14-foot) long and 1,225-kilogram (2,700-pound) whale was first spotted by fishermen near the northern island of Ingøya, not far from the Arctic city of Hammerfest, in April 2019 wearing a harness and what appeared to be a mount for a small camera and a buckle marked with text “Equipment St. Petersburg”.

That sparked allegations that the beluga was “a spy whale.” Experts said the Russian navy is known to have trained whales for military purposes.

Over the years, the beluga was seen in several Norwegian coastal towns and it quickly became clear that he was very tame and enjoyed playing with people, NRK said.

NGO Marine Mind said on its site that Hvaldimir was very interested in people and responded to hand signals.
