Angry Beaver

[Feuer Frei!]

Never heard that this could and is possible:

A fisherman has been bitten to death by a beaver after trying to take its photograph.
The man was on a fishing trip at Lake Shestakov in Belarus with two friends when they spotted the animal on the side of the road.
He stopped so that he could take a picture but as he approached the beaver it pounced on him, biting him in the thigh.
His friends attempted to stem the flow of blood from the wound but the animal’s bite had severed a main artery and the man, who came from Brest, bled to death.
