Vimlaben Patel died last Sunday in a fire at a Streatham Vale care home
The cause of a fire which killed a Norbury great-grandmother in a Streatham Vale care home is still being investigated.
Vimlaben Patel, 85, who lived in Aashna House in Bates Crescent, died in the blaze on Sunday evening.
A postmortem examination this week gave her cause of death as smoke inhalation.
But fire forensic teams are still unclear as to what caused the fire, and are still investigating at the scene.
Fire sources have said the blaze is believed to have started in Mrs Patel's room, but her family said she did not smoke, and was bedridden so did not use the kitchen.
Officers from Lambeth CID are also investigating.
