Chases after fellow in organised searches (8)
I believe the answer is:
manhunts
'searches' is the definition.
(manhunt is a kind of search)
'chases after fellow' is the wordplay.
'chases' becomes 'hunts' (hunting is a kind of chasing).
'after' is a charade indicator (letters next to each other).
'fellow' becomes 'man' (fellow can mean a man).
'hunts' after 'man' is 'MANHUNTS'.
'in organised' is the link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Another definition for manhunts that I've seen is " Searches for criminals".)
