Stole perhaps from gangster, one going missing (5)
I believe the answer is:
scarf
'stole perhaps' is the definition.
(stole is a kind of scarf)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for scarf that I've seen before include "Garment for wrapping; muffler" , "Stole" , "Something worn around the head or neck and shoulders" , "keep joints secure" , "Neck covering" .)
