Arrest, nab (4)
I believe the answer is:
nick
I believe this is a double definition.
'arrest' is the first definition.
(I've seen this before)
'nab' is the second definition.
(thesaurus)
(Other definitions for nick that I've seen before include "Score - police station" , "Nab; notch" , "Lift" , "Colloquially, a prison or police station" , "Appropriate" .)
