Rebuke for violent pub attack (7)
I believe the answer is:
upbraid
'rebuke' is the definition.
(I've seen this before)
'violent pub attack' is the wordplay.
'violent' indicates anagramming the letters.
'attack' becomes 'raid' (raiding is a kind of attacking).
'pub' with letters rearranged gives 'upb'.
'upb'+'raid'='UPBRAID'
'for' is the link.
(Other definitions for upbraid that I've seen before include "Scold over arid pub" , "Rebuke, scold severely" , "Criticise or scold" , "Chastise" , "Angrily reproach" .)
