Flier the police distributed close to Manchester (10)
I believe the answer is:
helicopter
'flier' is the definition.
(I've seen this before)
'the police distributed close to manchester' is the wordplay.
'distributed' indicates anagramming the letters.
'close to' says to take the final letters (the close/ending of).
The final letter of 'manchester' is 'r'.
'the'+'police'='thepolice'
'thepolice' with letters rearranged gives 'helicopte'.
'helicopte'+'r'='HELICOPTER'
(Other definitions for helicopter that I've seen before include "Chinook" , "surveillance equipment" , "Rotorcraft" , "aircraft" , "Triple echo (anag) - form of air transport" .)
