Police are appealing for public assistance to help locate missing elderly woman Doris Hahne.
It's believed the 86-year-old was last at her Darbyshire Street, Sunbury address on Tuesday 10 March.
That same day she spoke with family about 4pm, but has not been seen or made contact with family since.
She may be travelling in her silver 2006 Ford Falcon sedan registered UWI 166.
Police and family have concerns for Doris as her disappearance is out of character and as she has a medical condition which can cause her to become disoriented.
Investigators have released an image of Doris in the hope someone recognises her and can provide information regarding her current whereabouts.
Anyone who may have seen Doris or with information is urged to contact Sunbury Police Station on 9744 8111.
