The toddler found ablaze in Rainham today suffered 90 per cent burns.
Police are treating the horrific incident, in Simpson Road, as a “tragic accident”, a spokesman said.
The three-year-old girl was flown to Broomfield Hospital’s specialist burns unit by air ambulance, at around 10.25am for treatment.
A house in Simpson Road was cordoned off earlier today as detectives examined the scene.
A rug, possibly used to extinguish the flames, was visible in the driveway of the two-storey home.
Parts of a nearby green area, known to locals as New Park - where the air ambulance helicopter landed - were also closed to the public.
