A “high-risk” missing person has not been in contact with anyone since disappearing on Monday, say police.
David Barlow, 29, was last seen by family at an address in Walnut Tree at 9.30am three days ago.
Officers say they are concerned for his welfare due to his “state of mind” at the time he went missing.
Superintendent Gez Chiariello said a “robust structure” has been put in place surrounding the investigation, with officers “exploring every avenue” to find him.
So far they have used resources similar to a murder investigation - checking David’s financial records, as well as doing house checks in a bid to get him home as soon as possible.
Mr Chiariello said: “We are very concerned because it is very out of character.
“He is a high-risk so a number of appeals have gone out and we will do that until we find him and hopefully he will be safe and well.”
David is white, around 5ft7ins tall, slim, with short brown hair shaved on the side, cropped on top, with a brown beard.
Police now believe he may be wearing a navy blue River Island jacket, made from hoody-style material and with three light brown toggles down the front and silver poppers hidden underneath.
He is believed to be wearing a black zip cardigan with white t-shirt underneath and blue jeans and work boots.
If you see him, call 101, quoting URN 526 of 26/1.
