Stops repairs to rare streets (7)
I believe the answer is:
arrests
'stops' is the definition.
('arrest' can be a synonym of 'stop')
'repairs to rare streets' is the wordplay.
'repairs' indicates anagramming the letters (I've seen 'repaired' mean this).
'streets' becomes 'sts' (st is an abbreviation for street).
'rare' is an anagram of 'arre'.
'arre'+'sts'='ARRESTS'
(Other definitions for arrests that I've seen before include "made by police" , "collars" , "has a heart attack" , "Checks" , "Apprehends" .)
