Be told off having fled (6)
I believe the answer is:
bolted
'fled' is the definition.
(bolting is a kind of fleeing)
'be told off' is the wordplay.
'off' indicates an anagram.
'be'+'told'='betold'
'betold' with letters rearranged gives 'BOLTED'.
'having' acts as a link.
(Other definitions for bolted that I've seen before include "Fled, having locked up?" , "Fastened door with sliding bar (6)" , "Ran away" , "Absconded" .)
