Numerous calls to Triple Zero (000) were made for a Kia and Volkswagen Golf allegedly driving erratically around Dimboola Road about 5pm.

The 20-year-old Broadmeadows man was taken to hospital with serious injuries.
Four males were arrested and interviewed in relation to the incident.
A 15-year-old and 17-year-old from the Hume area, a 23-year-old Romsey man and a 24-year-old Sunbury man were released pending further enquiries.
It is understood a number of people left the scene prior to police arrival.
The investigation remains ongoing.
