John Pogias

Police are appealing for public assistance to help locate missing Reservoir man John Pogias.

The 83-year-old last spoke with family about 8am Tuesday morning (Apr. 28) but has not been heard from since.

Police and family hold concerns for his welfare due to a medical condition and his disappearance is out of character.

John may be travelling on foot and is known to frequent Coles on Edwardes St, Reservoir and cigarette stores in Preston.

He is described as 165cm tall with a thin build, white thinning hair and brown eyes.

Police have released an image of John in the hope someone may recognise him and provide information regarding his current whereabouts.
