Person raking in money in dock after court briefly disrupted (8)
I believe the answer is:
croupier
'person raking in money' is the definition.
(someone gathering money at a gambling table)
'dock after court briefly disrupted' is the wordplay.
'dock' becomes 'pier' (I've seen this before).
'after' says to put letters next to each other.
'briefly' means to remove the last letter.
'disrupted' indicates anagramming the letters.
'court' with its last letter taken off is 'cour'.
'cour' with letters rearranged gives 'crou'.
'pier' put after 'crou' is 'CROUPIER'.
'in' is the link.
(Other definitions for croupier that I've seen before include "Gaming table worker" , "Leisure worker" , "Betting employee" , "Person in charge of gambling-table" , "Worker raking it in at the casino!" .)
