Robs a bad West Indian island (8)
I believe the answer is:
barbados
'robs a bad west indian island' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for barbados that I've seen before include "holiday island" , "tropical island" , "Independent state in the West Indies" , "Island in West Indies, capital Bridgetown" , "Most easterly West Indies island" .)
