Suspect parted with explosive device (6)
I believe the answer is:
petard
'explosive device' is the definition.
(petard is a kind of explosive device)
'suspect parted' is the wordplay.
'suspect' indicates anagramming the letters.
'parted' is an anagram of 'PETARD'.
'with' acts as a link.
(Other definitions for petard that I've seen before include "A small bomb - you may be hoist with your own" , "Hoist with one's own -" , "Explosive device carried to blow in a door" , "Possession that one may be hoist with" , "Explosive device, one could have been hoist by their own, of old" .)
