Fellow went ahead and bolted (4)
I believe the answer is:
'bolted' is the definition.
(I've seen this in another clue)
'fellow went ahead' is the wordplay.
'fellow' becomes 'F' (abbreviation - of a society etc.).
'went ahead' becomes 'led' (I've seen this before).
'and' is the link.
(Other definitions for fled that I've seen before include "Did a runner" , "Left the field" , "Ran off in a hurry" , "dashed off elsewhere" , "Female showed the way and escaped" .)
