On the ground police are taking photos of cars and taking to witnesses.

The ABC understands the incident is not terror related.

Local resident Vijay Dantu, who lives opposite the police headquarters, recalls hearing gunshots.

“I was doing some work at my home and there’s a gun shot and I thought it was a tyre puncture,” he told the ABC.

“Then all of a sudden two more, two more shots came.”

More to come.
