Sounds like outlawed Italian criminal (6)
I believe the answer is:
bandit
'criminal' is the definition.
(bandit is a kind of criminal)
'sounds like outlawed italian' is the wordplay.
'sounds like' shows a homophone (sound like).
'outlawed' becomes 'banned' (banning is a kind of outlawing).
'italian' becomes 'it'.
'banned' is a homophone of 'band'.
'band'+'it'='BANDIT'
(Other definitions for bandit that I've seen before include "Violent outlaw" , "Armed robber in the Wild West" , "(One-armed?) outlaw" , "Outlawed robber" , "Armed outlaw" .)
