Outlaw died in gang (4)
I believe the answer is:
band
'gang' is the definition.
(I've seen this before)
'outlaw died' is the wordplay.
'outlaw' becomes 'ban' (banning is a kind of outlawing).
'died' becomes 'd'.
'ban'+'d'='BAND'
'in' acts as a link.
(Other definitions for band that I've seen before include "Ring or musical group (4)" , "Body" , "Pop group; stripe" , "Musicians - circle" , "company" .)
