A criminal set? (8)
I believe the answer is:
receiver
This clue is a double definition.
'a criminal' is the first definition.
(I've seen this before)
'set?' is the second definition.
(I know that receiver is a type of set)
(Other definitions for receiver that I've seen before include "Person dealing with property of bankrupt" , "Telephone handset" , "When a business fails, this person is appointed to liquidate or protects assets" , "Communications device" , "Person appointed to liquidate or preserve assets" .)
