Whatever happened to that Fortified Weed Coffee Shop in Kent?

I remember this being on the news a few years back, it was a coffee shop that sold weed somewhere in the south of Kent kind of near Worthing... I think...

The police tried to raid it a few times but the place was built like a brick shithouse so by the time the police got in all the weed had been thrown into a big furnace.

Does anyone know what happened to this place? Did they finally get busted? are they still around... Would be interesting to know...
