The group has a scoundrel again (5)
I believe the answer is:
cadre
'the group' is the definition.
The answer is an example.
'a scoundrel again' is the wordplay.
'a scoundrel' becomes 'cad' (cad is a kind of scoundrel).
'again' becomes 're' (prefix meaning 'again').
'cad'+'re'='CADRE'
'has' acts as a link.
(Other definitions for cadre that I've seen before include "activist group" , "Raced around with basic military unit" , "Nucleus of key personnel" , "Fighting unit" , "Small group of people trained for a purpose" .)
