Police raid broke statue, small, in bar (4)
I believe the answer is:
bust
'police raid' is the definition.
(eg a drugs bust)
'small in bar' is the wordplay.
'small' becomes 's' (abbreviation - e.g. clothes size).
'in' means one lot of letters goes inside another.
'bar' becomes 'but' (both can mean 'except for').
's' inserted within 'but' is 'BUST'.
'broke statue' is the link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for bust that I've seen before include "economic collapse" , "Sculpture of head and shoulders" , "item of statuary" , "Small statue" , "Piece of sculpture - broken!" .)
