Victim needing help, according to the announcer (6)
I believe the answer is:
sucker
'victim' is the definition.
(I know that sucker is a type of victim)
'help according to the announcer' is the wordplay.
'help' becomes 'succor' (succoring is a kind of helping).
'according to the announcer' indicates a 'sounds like' (homophone) clue.
'succor' is a homophone of 'SUCKER'.
'needing' acts as a link.
(Other definitions for sucker that I've seen before include "Gullible person; plant shoot" , "Underground shoot from shrub, or slang victim" , "Dupe" , "Fool" , "Slangy victim or plant shoot" .)
