An elderly woman whose husband was arrested on suspicion of her murder died as a result of neck injuries, police have said.
Betty Gallagher, 87, was found dead at her home on Cranmore Rise in Belle Isle on Sunday morning.
Detectives arrested an 85-year-old man – understood to be her husband Frank – at the scene.
It is thought he also required treatment for an injury.
A postmortem has now been carried out, showing Mrs Gallagher died of a neck injury, which is understood to have caused her to suffocate.
Following hospital treatment, Mr Gallagher has been released on bail while enquiries continue.
Neighbours described Mr and Mrs Gallagher, who have a son and a daughter, as a quiet couple who had struggled recently with health problems.
Mrs Gallagher was thought to be virtually house-bound because of severe arthritis. Mr Gallagher, who used to work at Leeds Prison in Armley, is believed to have developed dementia.
Jack Blades, 90, who has known Mr Gallagher for 60 years, said: “He is the most placid man you could ever meet.
“He was very quiet and introverted. When I heard about what happened I just couldn’t believe it.”
Another neighbour, who did not want to be named, said: “We have been here 64 years and they arrived a little after us but they were very quiet – they didn’t mix.
“It’s a terrible shock.”
A West Yorkshire Police spokesman said: “An 85-year-old man arrested at the scene has been bailed as police undertake a full forensic examination of the property to establish the full circumstances behind the incident. Police are not seeking anyone else in connection with the matter.”
