Rioting in each N Indian city (7)
I believe the answer is:
chennai
'indian city' is the definition.
(Chennai is a city in India)
'rioting in each n' is the wordplay.
'rioting' is an anagram indicator (I've seen this in other clues).
'in'+'each'+'n'='ineachn'
'ineachn' anagrammed gives 'CHENNAI'.
(Other definitions for chennai that I've seen before include "City previously called Madras" , "Indian port" , "Indian city, formerly called Madras" , "Current name for Madras" , "Official name for Madras" .)
