Resell illegally (5)
I believe the answer is:
scalp
'resell illegally' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for scalp that I've seen before include "Hirsute war trophy once taken by Native Americans" , "Hair producer" , "Cut hair very short" , "wants to resell theatre tickets" , "Token of victory" .)
