Unknown Vic attacker still on the run

A man wanted over a brazen stabbing in Melbourne last month is still on the run.

Police say a 42-year-old man was shopping in Reservoir on May 9 when the unknown attacker came from behind and stabbed him multiple times before fleeing in a red Volkswagen.

Investigators, on Saturday, released a FACE image of a man they hope will be able to help with their enquiries.
