Two men and a woman are on the run after police fired at a car that deliberately accelerated towards them in Melbourne's southeast.
Police say two men armed with a knife and a hammer were involved in a theft and assault at a Dandenong liquor store on Wednesday afternoon.
The men and a woman were later spotted in the car on the Princes Highway in Dandenong where it accelerated towards officers, and one shot was fired at the vehicle which was later found dumped.
The officers were uninjured and the investigation is ongoing.
The Professional Standards Command will oversee an investigation into the discharge of a firearm, police said in a statement on Thursday.
