Police are calling for the driver of a white ute to come forward, after a hit and run at Tweed Heads South overnight.
A 59-year-old woman was taken to hospital in a serious but stable condition, after getting hit on Minjungbal Drive around 8pm on Sunday.
The pedestrian suffered head and leg injuries in the crash, but the driver failed to stop and help.
Officers are hoping to speak with the driver of a late model, single-cab utility with a steel tray.
They are also hoping any witnesses to the crash will come forward, including the driver of a dark grey Ford Festiva and the rider of a white, sports motorcycle seen in the area at the time.
It's believed they may be able to assist in the investigation.
