Getting held up, maybe saw raid (4)
I believe the answer is:
loot
'raid' is the definition.
(I've seen this in another clue)
'getting held up maybe saw' is the wordplay.
'getting held up' is a reversal indicator (in a down clue, letters go up).
'maybe saw' becomes 'tool' (I've seen this before).
'tool' backwards is 'LOOT'.
(Other definitions for loot that I've seen before include "Tool for plundering" , "Prize" , "Tool found among plunder" , "Steal (goods); money" , "Stolen goods" .)
