Bagman

A bag man (or bagman), is a person designated to collect dirty money, e.g. in a protection racket. A bag man may also be known as a delivery boy or running man. Originally the term applied only to Mafia members collecting for mob bosses, but the term later spread to use in corrupt police precincts for patrolmen who picked up and delivered bribes from the local mob(s) to the precinct captain.
