One's prosecuted and released (6)
I believe the answer is:
issued
'released' is the definition.
('issue' can be a synonym of 'release')
'one's prosecuted' is the wordplay.
'one's' becomes 'is' (roman numeral).
'prosecuted' becomes 'sued' (I've seen this before).
'is'+'sued'='ISSUED'
'and' acts as a link.
(Other definitions for issued that I've seen before include "Circulated, a statement perhaps" , "Brought out a publication" , "Published and came forth" , "Turned out" , "Distributed - came forth" .)
