The driver responsible for the hit-run killing of a Dutch national is being harboured in Melbourne’s inner suburbs, according to police who say an arrest is imminent.

Detective Inspector Stuart McGregor says police have narrowed their search down to four suspects who match the description of the man caught on CCTV near Sunday's crash site.

All four are yet to be accounted for and most are already known to police.
