Detectives from the Moorabool Crime Investigation Unit say a a light blue EB model Ford Falcon was on the incorrect side of Trentham-Spring Hill Road before it forced the victim's vehicle onto grass beside the road.

The victim quickly returned to his vehicle and drove off as the other man pointed the firearm toward him.
Police have released an image of a man they wish to speak to.

He was wearing a knitted brown jumper, blue jeans and appeared scruffy in appearance.
