You couldn't make it up!

Customers at a branch of Barclay's Bank in a town in Essex were surprised to find that although the bank was open, there were no staff.  They were able to wander around, get behind the counter and into the back offices.  It's not known exactly how this happened, but perhaps the most disturbing aspect of the whole business is that, despite a 999 call reporting the matter, it took police over an hour to respond, and it was a further three hours before anybody from Barclay's turned up.  Luckily a few civic minded customers stood guard in the meantime.
