An elderly woman was found dead by firefighters called to tackle a blaze at her Primrose Hill flat.
Fire crews from Huddersfield made the grim discovery when they were called to the ground floor flat in Whitehead Lane in the early hours of Saturday morning.
Saddened neighbours said the frail woman, aged 74, lived alone and relied on the help of family and carers.
Police launched an investigation but said that the fire is not being treated as suspicious.
Two fire crews from Huddersfield fire station and a crew from Elland were alerted to the blaze just after 4am on Saturday.
They gained access to the flat with the help of family members who had a key.
The crews tackled a small fire in the bedroom where the woman’s body was found.
A spokesman for Huddersfield fire station said that the flat was badly damaged as it filled with thick, acrid smoke.
Police and an ambulance also attended in the aftermath of the tragedy.
At the weekend police were working with fire investigators to establish the cause of the fire.
On Saturday morning the smell of smoke still lingered in the air as crime scene investigators worked inside the visibly blackened hallway of the woman’s home.
Neighbours spoke of their sadness over her death.
One neighbour, who did not want to be named, said she was woken up by firefighters rushing to the scene.
“I was woken up at 4.15am and saw two fire engines,” she said. “The windows are all burned at the back – they are black with soot.
“It’s very quiet and nice round here and the flats are adapted for disabled people.
“I think the lady was quite poorly.
“She looked like she couldn’t move and as I walked past her window I would see her sat in her chair. It’s very sad.”
Another neighbour said he witnessed the incident after returning home from his late shift.
A firefighter had knocked to check if he was safe.
“Firefighters came and knocked on the door to check that the fire had not spread,” he said. “It’s really sad. Police told me that the lady had died.”
The neighbour explained that he had lived in the stone-built block of flats since they were built two years ago.
The woman who has lost her life on Saturday moved in shortly afterwards.
“I would see her sitting in her chair at home and doctors had been to see her recently.”
At the weekend firefighters returned to the Primrose Hill area to conduct fire safety checks at properties in the area.
Detective Inspector Ian Thornes, of Kirklees CID, confirmed that police were called following the fire.
He added: “Sadly, the occupant of the property, a 74-year-old woman was found deceased.
“There are no suspicious circumstances to the incident.
“The family have been informed.”
