Officer, male cop in complex (9)
I believe the answer is:
policeman
'officer' is the definition.
('policeman' can be a synonym of 'officer')
'male cop in complex' is the wordplay.
'complex' is an anagram indicator.
'male'+'cop'+'in'='malecopin'
'malecopin' anagrammed gives 'POLICEMAN'.
(Other definitions for policeman that I've seen before include "Menial cop (anag)" , "Constable" , "Constabulary member" , "Bobby" , "Open claim (anag.)" .)
