Reprimand for violent pub attack (7)
I believe the answer is:
upbraid
'reprimand' is the definition.
(upbraid can mean to reprimand or rebuke)
'violent pub attack' is the wordplay.
'violent' indicates anagramming the letters.
'attack' becomes 'raid' (raid is a kind of attack).
'pub' with letters rearranged gives 'upb'.
'upb'+'raid'='UPBRAID'
'for' is the link.
(Other definitions for upbraid that I've seen before include "Scold, reproach" , "Condemn" , "Chastise" , "Reprove" , "Beam used for detection of aircraft" .)
