A hoverboard had been charging inside a bedroom when a fire broke out, damaging the floor underneath it, according to the London Fire Department.

Cecilia Macedo was shaken after her 10-year-old daughter's hoverboard exploded.

A fire that killed a toddler and critically injured two others, and also led to critical injuries to a responding fire official, appears to have been sparked by a recharging hoverboard, authorities said.
