He is described as white, approximately 5ft 9, of slim build with grey receding hair and is believed to be wearing a green coat, tan coloured trousers and brown shoes.

Chief Inspector Rob Button said: "We are concerned for John’s welfare given the circumstances. He has been missing for more than 24 hours now and given the temperatures outside, along with the fact he is vulnerable, he could be feeling quite scared.

“We have now released images of John in the clothing we believe he is currently wearing and would therefore urge members of the public to keep an eye out for him.”

Anyone who may have seen Mr Boyd or knows of his current whereabouts should contact Norfolk Police on 101, quoting incident 210 of 4 January 2022.
