Squirrel on rampage

One is afraid of big animals such as wild dogs, lions, tigers, snakes, etc. It is far easier to live in a city as such dangerous animals are not present in the city, and the only thing you need to be afraid in the city are other humans, whether the are muggers, careless drivers or junkies. You do find very cute animals in the city, such as small birds, puppies, cute cats, and even wilder animals such as squirrels and racoons. However, even such a small animal such as a squirrel can become dangerous:

An aggressive squirrel attacked and injured three people in a German town before a 72-year-old pensioner dispatched the rampaging animal with his crutch.
The animal then entered a building site and jumped on a construction worker, injuring him on the hand and arm, before he managed to fight it off with a measuring pole.

It takes a lot for a small animal such as this one to become agitated; doubtless there must have been some of irritation caused to the squirrel for it to become violent like this one did.
