Commital to custody (6)
I believe the answer is:
remand
'commital to custody' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for remand that I've seen before include "Place of detention for those awaiting trial" , "Place of detention for young offenders" , "Commital to custody" , "Return prisoner to custody pending further investigation" , "Send back, into custody say" .)
