It's interesting - Southwark Towers [which was knocked down to make way for the Shard] was where I used to work, before we got moved out due to the Shard project being started.
The media latched onto a story a couple of months ago about a fox living in the Shard. Google Romeo the fox or see this link from the Metro:
