'contract killing in india' is the definition.
I know nothing about this answer so I can't judge whether this works.

'leader of upstarts in riotous paris' is the wordplay.
'leader of' suggests taking the first letters.
'in' is an insertion indicator.
'riotous' indicates anagramming the letters.
The first letter of 'upstarts' is 'u'.
'paris' with letters rearranged gives 'spari'.
'u' put within 'spari' is 'SUPARI'.

'for' is the link.
