"Police have been advised that a black hatchback vehicle and a white utility were seen in the vicinity at the time.

"Detectives are continuing their investigation into the matter."

One Hopetoun St resident, who asked not to be named, said he saw the drivers of two cars exchange goods in the street before driving to the back entrance of the Mill Point Road house about 10pm yesterday.

"There was a woman in the driveway who was shouting and waving. She was refusing them entry, telling them to go," he said.

The man said both cars then quickly drove away and he heard three shots fired over a 15-second period.
