I believe the answer is:

despoil

I'm a little stuck... Click here to teach me more about this clue!

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

I can't explain the rest of the clue.

(Other definitions for despoil that I've seen before include "Steal from (a place)" , "Plunder - piled so (anag)" , "sack" , "strip" , "Ravage" .)

I've seen this clue in The Hindu.
