Supplied from a safe distance (3)
I believe the answer is:
fed
'supplied' is the definition.
(feeding is a kind of supplying)
'from a safe distance' is the wordplay.
'from' indicates a hidden word.
'FED' is hidden in the letters of 'safe distance'.
(Other definitions for fed that I've seen before include "Given food to eat" , "Dished up food" , "US agent" , "Banking authority" , "Given sustenance" .)
