Swindle crowd (6)
I believe the answer is:
hustle
I believe this is a double definition.
'swindle' is the first definition.
(hustle is a kind of swindle)
'crowd' is the second definition.
(thesaurus)
(Other definitions for hustle that I've seen before include "Put pressure on - sleuth (anag)" , "Frenzied activity" , "Jostle; hurry; swindle" , "Hurry like sleuth" , "Jostle, push around." .)
