London police say the cladding from a tower block that was engulfed in flames, killing scores of people, has failed all safety tests. Police detectives are now considering manslaughter charges as well as criminal offenses. The Metropolitan Police say they are reviewing every company involved in the building and refurbishment of Grenfell Tower. Scotland Yard has also revealed that the blaze started in a fridge freezer, but it was not started deliberately. At least 79 people were killed in the fire that burnt down the tower block on June 14. Police, however, fear the number may rise. Downing Street has been under pressure for its handling of the aftermath of the blaze.
