A house will be demolished in an attempt to find an elderly woman who is missing after a fire at the property.
Emergency services were called to a fire at a building in Beacon Heath, Exeter, on Monday.
Police said extensive damage had made the property unsafe and an 89-year-old woman was "unaccounted for".
Det Insp Vicky Goff said: "In order to locate her, the house will be demolished in a systematic and controlled way over the next few days."
She added the woman's family were being supported by police.
The inspector said the incident "appears to be accidental".
A police cordon remains in place.
