Roof Art ?

I'm led to believe that the owner of this property was refused planning permission for a loft conversion, so just to "cock a snook" at the Local Authority Planning Dept this was installed.
 I quite like the shark, and also the story whether it is true or not.
Update, I have just Googled it, as I was in a rush to load the blip there is the story here.
