Look at the frosted panel closely and you'll notice that there are sections that are flat edged (as if to attach the frosted piece onto the assembly). Take a screwdriver, insert it into the tabbed section and slowly prise it out. Should come off pretty easily (a LOT easier then them bastard electrical connectors).

Well I got it off. Thanks guys, though didn't know about the 3 screws holding it on. I couldn't work out why it wasn't coming off until I took the light cover off! Cheers.
