Police said an occupant was inside the flat at the time of the shooting, but was not injured.

It was not clear if the shot was fired from someone standing outside the window, or from a moving car.

Fairfax Media spoke to several people living in the flats on Wednesday morning, however none of them heard any disturbances prior to police knocking on their doors.

Forensic investigators remain at the scene on Wednesday morning.
