An electric bicycle is thought to have been the cause of fire at a tower block in England, investigators said.
A man is believed to have fallen to his death after climbing out of a window to escape the blaze in Bristol on Sunday.
Emergency services were called to the blaze on the top floor of Twinnell House in the Easton area of the city shortly after 2.15am.
Eight people were treated in hospital, and one continues to receive treatment for minor burns.
Around 90 residents were evacuated and a rest centre was set up.
Bristol City Council housing officers are continuing to provide support to those affected.
The road has now reopened, the tower block has been declared safe and the cordon lifted.
Avon Fire and Rescue area manager Steve Quinton, who conducted the fire investigation, said the fire prevention measures, including external cladding, worked and contained the blaze to the flat where it began.
“Fire Investigators identified the cause of the fire as accidental, due to an electric bike,” he said.
“Fire investigation revealed that smoke alarms were provided in the property and electrics wired in by the landlords.
“After seeing the tragic fire, understandably, local people are concerned about fire risk in their own homes, whether they live in flats in the city or otherwise.
“If you’re concerned about fire safety in your home, one of the most important things to do is to make sure your escape routes are clear and ensure that everyone living in the property knows how to get out in the event of an emergency.”
Local councillor Tom Renhard added: “We’d like to offer our condolences to the family and friends of the person who sadly lost their life on Sunday.
“Many people will feel affected by this tragedy, and I’d encourage residents to seek support from the council’s housing team who will continue checking in on everyone.”
