Roughly arresting sons for crime (13)
I believe the answer is:
transgression
'crime' is the definition.
(thesaurus)
'roughly arresting sons' is the wordplay.
'roughly' indicates an anagram.
'arresting'+'sons'='arrestingsons'
'arrestingsons' with letters rearranged gives 'TRANSGRESSION'.
'for' is the link.
(Other definitions for transgression that I've seen before include "Offence" , "Wrongdoing" , "something bad going on?" , "Wrong" , "Infringement; sin" .)
