And now the beavers get into the act:

First squirrels, rodents, raccoons, and other animals ... and now:

Angry beavers have managed to successfully scare off the locals after taking over a bathing area in Lindesberg in central Sweden. But local authorities have vowed to exterminate the current batch of river-dwelling rodents.

The most recent incident came at the weekend as three generations of the same family were out enjoying a swim in the Bottenån river.

A mother and her two children could only look on in horror as a beaver went on the attack, biting the children's grandmother until she bled. The older woman was also struck by the beaver's tail and was left needing hospital treatment, Nerikes Allehanda reports.

There have previously also been reports of a beaver attacking a child on the same stretch of water.

Not everybody is prepared for attacks of this kind, as beavers are generally regarded as being somewhat shy animals.

Yeah? You and whose army?
