Officials in Russia are baffled by the fact that someone spray-painted a polar bear.
Footage shared on social media in Russia shows the polar bear with "T-34" spray-painted in black on its side. Experts warned the stunt could affect the animal's ability to blend in with its surroundings and hunt for food.
An investigation is underway to determine exactly where in Arctic Russia the video was filmed.
The T-34 was a tank that played a vital role in the Soviet Union's defeat of Nazi Germany in World War Two.
The footage was posted on Facebook by Sergey Kavry, a member of the World Wildlife Fund nature organization, and then shared by local media.
A scientist said it was unlikely that the bear could have been painted without it being sedated.
He said the bear could not have been mobile, or at least must have been quite still while it was being sprayed because "the characters are evenly written and are all the same size."
