Like a number of others here, the brown box on our outside wall has been vandalised - we are in a flat fronted property that opens on to the road so the public have access and somebody has kicked the cover off exposing all the cables. The cover has gone missing!

There are also several loose wires which hang down the side of the building, they protrude though a cavity in the exterior wall which corresponds to the small, white virgin box inside the property. I believe that these were originally connected to the broken brown exterior box, but obviously have come loose and need removing also:
