Crossword Genius

Fighter delighted a riot's broken out (9)

Ross

I believe the answer is:

gladiator

'fighter' is the definition.
(I've seen this before)

'delighted a riot's broken out' is the wordplay.
'delighted' becomes 'glad' (I've seen this before).
'broken out' indicates an anagram.
'a'+'riot'='ariot'
'ariot' anagrammed gives 'iator'.
'glad'+'iator'='GLADIATOR'

(Other definitions for gladiator that I've seen before include "Warrior" , "Roman arena combatant" , "One trained to fight in Roman arenas" , "Circus performer" , "Film" .)

I've seen this clue in The Telegraph.
