Members of the public are being encouraged to join in the search to help find a 46-year-old Norfolk police officer who is missing.

Police remain extremely concerned for the welfare of their colleague Adrian (known as Ady) Porter, who formerly worked in King’s Lynn, could be in the North Norfolk area.

He was last seen at his home in Holt at around 8am on Monday.
