Police raid not working (4)
I believe the answer is:
bust
I believe this clue is a double definition.
'police raid' is the first definition.
(I've seen this in another clue)
'not working' is the second definition.
(bust can mean broken)
(Other definitions for bust that I've seen before include "Financially ruined" , "Portrait - broken" , "Upper body goes bankrupt" , "Raid - boobs" , "Sculpture of head and chest" .)
