Idiot was troubled, being attacked (8)

I believe the answer is:

assailed

'being attacked' is the definition.
(I've seen this before)

'idiot was troubled' is the wordplay.
'idiot' becomes 'ass' (I've seen this before).
'was troubled' becomes 'ailed'.
'ass'+'ailed'='ASSAILED'

(Other definitions for assailed that I've seen before include "charged" , "became aggressive" , "Attacked, lashed out" , "Set upon" , "Under attack" .)

I've seen this clue in The Guardian.
