Attend case of indictment and get out (4,2)
I believe the answer is:
beat it
'get out' is the definition.
(I've seen this before)
'attend case of indictment' is the wordplay.
'attend' becomes 'beat' (I've seen this in other clues**).
'case of' means to remove the middle letters (outsides of).
'indictment' with its centre removed is 'it'.
'beat'+'it'='BEAT IT'
'and' is the link.
(Other definitions for beat it that I've seen before include "Scram, take a powder" , "fly away" , "Make off hastily" , "Clear off!" , "leave" .)
