Police are appealing for help in finding missing 58-year-old James (Jim) Lewis.
Jim, who had lived in the Donaghadee area, was last seen at Holywood train halt on November 1 at 01.30.
He had been wearing a grey thermal top, grey jogging bottoms, skecher trainers, a flat cap and a blue snood.
He has also been carrying plastic shopping bags.
In a post on PSNI Facebook, officers say that Jim "now has a beard and longer hair in contract to the picture".
They ask the public to contact Newtownards PSNI on 101 and quote reference 1471 of 04/11/2019 with any information.
