JOIN USAsiyah Khan had arrived in the country earlier this year and was living with her husband Naveed, mother-in-law and two sisters-in-law.
The family of the woman which went out shopping, found the house locked when they returned home. The girl's husband then climbed over the gate only to find his wife's charred body in the back garden, the Daily Mail reported.
One of the family's neighbours said the victim's husband came screaming for help and she rushed with him to his house and found the body in garden but there were no flames.
"Nav came round to get me saying 'help me, help me'. I didn't know what to expect when I got round there, I thought she might have fallen over or the baby was coming early.
I thought I'd have to be a midwife.
"When I got into the garden, I just didn't know what to do with him – he was hysterical, the sisters were hysterical and the mother was too," she said.
"There were no flames, the body was just black and you could see bits of her clothes around," she added. Emergency services were called to the residential street in Bradford but the woman was pronounced dead at the scene.
Police were investigating the incident and it was not clear whether the woman had set herself on fire or had been set alight by someone else. No one has been arrested in connection with her death.
According to the neighbours the woman was rarely seen outside the house and did not speak English. The neighbours said they did not hear any screams.
The West Yorkshire police is investigating the case and a post-mortem examination was carried out to try to determine the exact cause of her death.
Police were called in by firefighters who had responded to reports of a fire at the house at about 7.15 pm on Thursday. "It's shocking – you don't expect that around here because it's a quiet neighbourhood," said a neighbour.
