More pictures have been released in the search for a sex offender who is a suspect in the murder of a 77-year-old Northumberland woman.
Northumbria Police are hunting for Graeme Jarman, 47, over the murder of Judith Richardson in Hexham.
The pictures show Mr Jarman in a Ladbrokes betting shop, in Saltburn, on Teesside on 22 August.
He went missing from his County Durham home shortly before Miss Richardson was found dead at her home.
Police have described Mr Jarman as "a risk to the public" and have urged people not to approach him.
He disappeared from his home in Delves Lane, Consett, on 17 August.
Miss Richardson was found dead at her home two days later by police officers returning her stolen handbag, which was found in Newcastle city centre.
She had been the victim of a "brutal" hammer attack.
Mr Jarman was last seen on a bus in Stockton-on-Tees on 26 August.
CCTV footage previously released by police shows him in Sainsbury's, in Yarm, at about 19:00 BST on 24 August.
Det Ch Supt Neil Adamson, from Northumbria Police, said of the latest pictures: "We are circulating these images to all forces in order to generate further public awareness of Graeme Jarman.
"Although the image is prior to his last confirmed sighting, it is the clearest image we have of him and we hope people may recognise him."
Officers from Durham and Cleveland Police are also involved in the inquiry and his details have been circulated to all UK forces.
Mr Adamson said: "We are working with forces across the country to locate this man as we are keen to speak to him in connection to the murder of Hexham pensioner, Judith Richardson.
"We urge anyone to contact Northumbria Police or their local force should they see this man. He should not be approached by the public as it is believed he could be a risk to himself and others."
Mr Jarman's mother Irene, 71, earlier urged him to hand himself in to police.
