A fridge had been one theory behind what caused the blaze before Metropolitan Police announced its findings. A resident of Grenfell Tower had been overheard telling people that his fridge started the fire.

Police are still trying to determine how the June 14 blaze spread so quickly. So far, samples of cladding and insulation collected from the building have failed safety tests.
