Police are calling for public assistance to help locate missing Travancore man Brian.
The 73-year-old was last seen at a Little Princess Street address about 1.30pm yesterday.
There are concerns for Brian's welfare due to the cold weather conditions, his age and he has dementia.
Brian uses a four-wheel walker to get about which it's believed he took with him.
He may be trying to travel to Glen Iris or Glen Waverley and is known to use public transport.
He is described as Caucasian, 168cm tall, with a slim build, full grey beard worn in a ponytail and a long grey ponytail.
He was last seen wearing glasses, a black t-shirt and pants.
Investigators have released an image of Brian and urge anyone with information on his whereabouts to contact Flemington Police Station on 9371 6100.
