Dave Harper, who works for the BBC in Cardiff, spotted these shenanigans and managed to snap this photo. 'Why does it take six burly blokes to manhandle the Tardis into position?' he wondered, bearing in mind it's just an empty prop. 'Maybe because it's heavier on the inside than it is on the outside,' I oh-so-wittily suggested.
Presumably, the iconic Police Box is being shoved up there to grab some attention in advance of the new season starting on Saturday.
Many thanks to Dave for letting me post this - yes, I will buy you a pint!
