Positive response in murder suspect Graeme Jarman hunt
Detectives said they had received more than 70 calls in their search for a sex offender who is a suspect in the murder of a 77-year-old Northumberland woman.
Northumbria Police are leading the hunt for Graeme Jarman, 47, in connection with the murder of Judith Richardson in Hexham.
They have also released CCTV footage of Mr Jarman at a supermarket in Yarm.
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 went missing from his home in Delves Lane, Consett, on 17 August.
Miss Richardson was found dead at her home on 19 August 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 Friday.
The new CCTV footage 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: "We have had a really positive response from the public.
"We have had more than 70 calls about potential sightings of this man and we are following up all enquiries.
"However, we do still urge people to come forward with information about Jarman's current whereabouts."
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: "It is possible this man may no longer be in the North East and we ask anyone who may have sighted Jarman to contact us or their local police force.
"We are working tirelessly to locate Graeme Jarman and continue to pursue a number of lines of enquiry."
Earlier Mr Jarman's mother Irene, 71, urged him to hand himself in to police.
