An electric bicycle is thought to have been the cause of fire at a tower block, investigators said.
A man is believed to have fallen to his death after climbing out of a window to escape the blaze in the Easton area of Bristol on Sunday.
Emergency services were called to the blaze on the top floor of Twinnell House on Wills Drive, off Stapleton Road shortly after 2.15am.
Eight people were treated in hospital, and one continues to receive treatment for minor burns.
Bristol City Council housing officers are continuing to provide support to those affected.
Wills Drive has now reopened, the tower block has been declared safe and the cordon lifted.
“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.”
Councillor Tom Renhard, Bristol City Council cabinet member for housing delivery and homes, 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.”
