Criminal seducer liberated (7)
I believe the answer is:
rescued
'liberated' is the definition.
(I've seen this in another clue)
'criminal seducer' is the wordplay.
'criminal' indicates an anagram.
'seducer' anagrammed gives 'RESCUED'.
(Other definitions for rescued that I've seen before include "Saved (from danger)" , "set free" , "Extricated" , "Secured (anag.)" , "Saved from - seducer (anag)" .)
