Neighbours have spoken of their shock after a young woman, thought to be pregnant, died after she was found on fire behind a house.
The 23-year-old woman was found with serious burns at the property in Cloudsdale Avenue, Bradford, at 7.15pm on Thursday. She was pronounced dead at the scene.
Detectives are investigating the death and are waiting for the results of a post-mortem examination. A spokesman said: "We are trying to establish the circumstances."
A cordon sealed off around eight houses from the main street, including the terraced property where the incident is believed to have taken place.
There was little evidence of what had happened at the front of the house, where one policeman stood guard at the front door. Three officers were seen going into and out of the house.
Neighbours said the area was usually quiet and peaceful and a close community, but some mystery surrounded the woman who died.
Aziza Kahn, who lives nearby, said she believed the woman was pregnant and lived at the property with her husband, mother-in-law and two sisters-in-law.
She said: "We never saw her (the woman). There was a time we were quite close to that family but not now. We didn't know her, we never got to talk to her. You never saw her with her husband, never ever saw them together. She was a young girl, we thought she was about 17 or 18, and she was pregnant."
Another neighbour, Rahana Kosar, said she believed the woman was Asian and had been in the UK for less than a year but said she rarely came out of the house.
She also said her family had had an argument with the woman's family in the past about car parking and had kept out of each other's way since then.
