Detectives investigating the death of a man in County Durham have released images of a man they need to trace.
Officers are keen to speak to the potential witness in connection with the death of David Cameron in Consett last month.
It is believed the unknown man was walking down Medomsley Road, near to The Braes Bar, when he may have seen Mr Cameron.

A short time later Mr Cameron was involved in an altercation in Southernwood, at about 5.33pm on December 5.
The 47-year-old was sadly pronounced dead a short time later at the scene.

A 14-year-old boy arrested in connection with the incident and is currently on conditional bail.
A spokesperson for Durham Constabulary said: "The man is being treated purely as a witness and is not in any trouble.

"The unknown man or anyone else who was in the area at the time is asked to get in touch with detectives at Durham Constabulary on 101."
