Risk complete outrage (8)
I believe the answer is:
endanger
'risk' is the definition.
(to risk is to put in danger)
'complete outrage' is the wordplay.
'complete' becomes 'end' (complete means to finish or end).
'outrage' becomes 'anger' (I've seen this in another clue).
'end'+'anger'='ENDANGER'
(Other definitions for endanger that I've seen before include "Dan Green (anag.)" , "Threaten" , "Place into peril, jeopardise" , "Put in peril" , "Put someone at risk" .)
