Police announce list of charges (4)
I believe the answer is:
bill
This clue is a quadruple definition!!
'police' is the first definition.
(informal term for UK police)
'announce' is the second definition.
(I've seen this before)
'list' is the third definition.
(I have seen 'List of charges' mean 'bill' so perhaps 'list' could also mean 'bill')
'of' acts as a link.
'charges' is the fourth definition.
(thesaurus)
(Other definitions for bill that I've seen before include "The fellow" , "Chap" , "statement of money owed" , "beak demanded" , "Piece of legislation -- one of the Clintons" .)
