Stops creeps regularly entering crafts (7)
I believe the answer is:
arrests
'stops' is the definition.
(arrest is a kind of stop)
'creeps regularly entering crafts' is the wordplay.
'regularly' means one should take alternating letters (regularly take one letter, leave next etc.).
'entering' is an insertion indicator.
'crafts' becomes 'arts' (I've seen this in another clue).
The alternate letters of 'creeps' are 'res'.
'res' placed into 'arts' is 'ARRESTS'.
(Other definitions for arrests that I've seen before include "made by police" , "Checks" , "has a heart attack" , "Stops and takes into custody" , "collars" .)
