Shoots up in making an arrest (4)
I believe the answer is:
stop
'arrest' is the definition.
(I know that arrest is a more specific form of stop)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for stop that I've seen before include "Hold on" , "Block; end; group of organ pipes" , "high card in bridge" , "break" , "Discontinue (an action)" .)
