Spy on street creating trouble (6)
I believe the answer is:
molest
'trouble' is the definition.
(I've seen this before)
'spy on street' is the wordplay.
'spy' becomes 'mole' (mole is a kind of spy).
'on street' becomes 'st' (I've seen this in other clues).
'mole'+'st'='MOLEST'
'creating' acts as a link.
(Other definitions for molest that I've seen before include "Harry" , "Fame" , "Assault in motels" , "Bug" , "Handle roughly, torment" .)
