Controlling what one arrested may be given (2,6)
I believe the answer is:
in charge
This clue is a double definition.
'controlling' is the first definition.
(synonyms)
'what one arrested may be given' is the second definition.
(an arrested person is charged)
(Other definitions for in charge that I've seen before include "Taking command" , "position of authority" , "Having overall control" , "At the helm" , "Leading" .)
