According to the Police reports, the Grenfell Tower fire in London started in a fridge freezer, and outside cladding and insulation failed safety tests, BBC reports.
The Police are going to consider manslaughter, health and safety and fire safety charges.
The government has ordered immediate testing of the Hotpoint fridge freezer that was involved.
