Chaps in the wrong newspaper boss harassed (9)
I believe the answer is:
tormented
'harassed' is the definition.
(torment can mean to harass or bother)
'chaps in the wrong newspaper boss' is the wordplay.
'chaps' becomes 'men' (chap means a man).
'in' is an insertion indicator.
'the wrong' becomes 'tort' (legal term).
'newspaper boss' becomes 'ed' (short for editor).
'men' put within 'tort' is 'torment'.
'torment'+'ed'='TORMENTED'
(Other definitions for tormented that I've seen before include "Distressed" , "Angst-ridden" , "Made to suffer" , "Suffering severely" , "Caused to suffer" .)
