Stop and take into custody (6)
I believe the answer is:
arrest
I believe this is a triple definition!
'stop' is the first definition.
(I know that stop can be written as arrest)
'and' acts as a link.
'take' is the second definition.
(I've seen this before)
'into' acts as a link.
'custody' is the third definition.
(I've seen this in another clue)
(Other definitions for arrest that I've seen before include "Bring to a standstill" , "Apprehend; detain" , "Collar" , "Stop (on suspicion)" , "Seize (a crime suspect)" .)
