Individual breaking racket eliminated (4,2)
I believe the answer is:
'eliminated' is the definition.
(to do someone in is to kill them)
'individual breaking racket' is the wordplay.
'individual' becomes 'one' (an individual is one person).
'breaking' means one lot of letters goes inside another.
'racket' becomes 'din' (both can mean a loud noise or disturbance).
'one' placed within 'din' is 'DONE IN'.
(Other definitions for done in that I've seen before include "Utterly exhausted" , "physically exhausted" , "completely exhausted" , "Spent" , "whacked" .)
