Release gang without charge (3,4)

I believe the answer is:

set free

'release' is the definition.
(synonyms)

'gang without charge' is the wordplay.
'gang' becomes 'set' (set of people).
'without charge' becomes 'free' (sold at no cost).
'set'+'free'='SET FREE'

(Other definitions for set free that I've seen before include "Released" , "Release, remove restraints" , "Deliver - release" , "without the box" , "no longer detained" .)

I've seen this clue in The Sun and The Telegraph.
