A flat fire that killed a woman and two young children is believed to have started accidentally and the most probable cause was an e-bike that was charging, the fire service has said.
Gemma Germeney, 31, died at the scene in Sackville Close, Cambridge, in the early hours of Friday, Cambridgeshire Police said.
Lilly Peden, aged eight, and four-year-old Oliver Peden were taken to hospital where they both later died, the force said.
