Help with technique identifying face on boy (7)
I believe the answer is:
benefit
'help' is the definition.
(I know that benefit is a type of help)
'technique identifying face on boy' is the wordplay.
'technique identifying face' becomes 'e-fit' (electronically generated face of crime suspect).
'on' says to put letters next to each other.
'boy' becomes 'ben' (boy's name).
'efit' after 'ben' is 'BENEFIT'.
'with' acts as a link.
(Other definitions for benefit that I've seen before include "Advantage or profit gained from something" , "Good" , "Fine bet (anag)" , "Payment" , "Fine bet on to produce an advantage" .)
