Editor went mad and ran amok (6)
I believe the answer is:
rioted
'ran amok' is the definition.
(I've seen this in another clue)
'editor went mad' is the wordplay.
'went mad' is an anagram indicator (I've seen 'going mad' mean this).
'editor' is an anagram of 'RIOTED'.
'and' acts as a link.
(Other definitions for rioted that I've seen before include "Of crowd, ran amok" , "Brawled" , "Revolted" , "was disorderly" , "Of mob, ran wildly through the streets" .)
