A killer has vanished from a secure unit.

Steven Dunne, 42, who stabbed Gordon Stalker to death at the door of his home in Elm Grove, Brighton, was reported missing after failing to return to Southview Low Secure Unit at around 5pm on Wednesday.

He was receiving treatment at the unit, after being convicted of manslaughter by diminished responsibility and ordered by the court to be detained under the Mental Health Act.

Detective Inspector Rob Morland said: "We are concerned for Steven's welfare and would urge him to get in touch.

"We believe Steven to be in the Brighton area and neighbourhood officers are working with partnership agencies to locate Steven.

"If you see Steven, please contact police immediately."

A spokeswoman from the Sussex Partnership NHS Foundation Trust said: "Mr Dunne has been assessed by his clinical team and poses a low risk to himself and to the public, however, it is important he takes regular medication and will need to return to hospital as soon as possible."

Steven is described as white northern European, 5'4, short brown hair, blue eyes, stocky, wearing a red t-shirt, black trousers and blue trainers.

Steven or anyone who sees someone matching his description is asked to contact Sussex Police on 0845 60 70 999 quoting serial 1332 of 28/9.
