Grenfell Tower blaze sparks manslaughter probe in London
London police consider manslaughter and other charges over the Grenfell Tower fire that killed 79 people or left missing. Investigators say exterior cladding failed safety tests and that the Hotpoint refrigerator may have ignited the blaze. Authorities urge building owners to test cladding. 14 buildings have shown combustible materials. Public appeals for information continue as tributes grow at a makeshift memorial.
