A tour riots disrupted? That's untrue (10)

Ross

I believe the answer is:

traitorous

'untrue' is the definition.
(thesaurus)

'a tour riots disrupted?' is the wordplay.
'disrupted?' is an anagram indicator.
'a'+'tour'+'riots'='atourriots'
'atourriots' is an anagram of 'TRAITOROUS'.

'that's' acts as a link.

(Other definitions for traitorous that I've seen before include "Unfaithful" , "committing treachery" , "Disloyal" , "throwing down the Emperor?" , "Betraying" .)

I've seen this clue in The Telegraph.
