Checks, made by police (7)
I believe the answer is:
arrests
I believe this clue is a double definition.
'checks' is the first definition.
('arrest' can be a synonym of 'check')
'made by police' is the second definition.
(I've seen this before)
(Other definitions for arrests that I've seen before include "made by police" , "Seizes and takes into custody" , "has a heart attack" , "Apprehends" , "Checks" .)
