Sought help from tutor, failing to restrain Scots hooligan (6,2)
I believe the answer is:
turned to
'sought help from' is the definition.
(I've seen this in another clue)
'tutor failing to restrain scots hooligan' is the wordplay.
'failing' indicates an anagram (a failed spelling of the word).
'to restrain' means one lot of letters goes inside another.
'scots hooligan' becomes 'ned' (Scottish term for a hooligan).
'tutor' anagrammed gives 'turto'.
'turto' placed around 'ned' is 'TURNED TO'.
(Other definitions for turned to that I've seen before include "Set to work" , "Sought advice from" .)
