Police investigating the separate murders of a 50-year-old woman and an 81-year-old man have released the name of the man they are seeking.
More than 100 officers are involved in the search for James Allen, 35, following the deaths of Colin Dunford, in Middlesbrough, on Monday, and Julie Davison, in Whitby, North Yorkshire, on Wednesday. Detectives described the killings as "two brutal murders in the victims' own homes".
The Cleveland and North Yorkshire forces issued a joint appeal to find Allen, who is known to police. Both victims were said by police to have suffered "serious head injuries".
