Haul in (6)
I believe the answer is:
arrest
'haul in' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for arrest that I've seen before include "Stop, check (progress)" , "Stop - take into custody" , "Stop (on suspicion)" , "apprehend a law-breaker" , "Take into custody as police do" .)
