Police searching for convicted sex attacker Graeme Jarman are following up hundreds of leads in a bid to find him.

Jarman, 47, who moved to Oxford in 2002, slept rough in the city until he robbed a woman at knifepoint in Wallingford.

He is now wanted in connection with the murder of a 77-year-old pensioner.

Jarman, described as “violent and dangerous” by police, was last seen on Friday, a week after Judith Richardson’s body was discovered at her home in Hexham, Northumberland.

Police said they had received more than 200 calls from the public.
