Anger in local leading to assault (7)
I believe the answer is:
barrage
'assault' is the definition.
(barraging is a kind of assaulting)
'anger in local leading' is the wordplay.
'anger in' becomes 'rage' (rage is a kind of anger. I am not sure about the 'in' bit.**).
'local' becomes 'bar' (I've seen this before).
'leading' is a charade indicator (letters next to each other).
'rage' after 'bar' is 'BARRAGE'.
'to' acts as a link.
(Other definitions for barrage that I've seen before include "Artificial obstruction in a river" , "Heavy bombardment" , "Sustained attack - means of damming river" , "Deterrent to low-flying air attacks" , "a lot of shells" .)
