Police are searching for James Mainland who is reported missing from his home in Orkney.
The 88-year-old male, who suffers from dementia, left his Island home in Birsay Orkney at 6.30am yesterday.
James is described as 5ft 8 inches tall, slim build with blue eyes, short white hair and a short white beard. At the time he left home he was wearing a blue body warmer, purple top, black trousers and brown slippers.
Police are also asking for all members of the public living in the Birsay area to check their garages and outhouses in case he has taken shelter somewhere.
A spokesman said: “It is believed that James will keep to the Birsay area and will hide from members of the public and may be violent if approached by people he does not know.
“We request that should anyone see James, then they should call 101 as soon as possible.”
