Recognise and arrest (9)
I believe the answer is:
apprehend
This clue is a double definition.
'recognise' is the first definition.
(thesaurus)
'arrest' is the second definition.
('apprehend' can be a synonym of 'arrest')
'and' acts as a link.
(Other definitions for apprehend that I've seen before include "Arrest (someone)" , "Arrest - grasp" , "Recognise - arrest - suspect" , "Detain" , "nick" .)
