The Metropolitan Police announced they will submit files to the Crown Prosecution Service recommending criminal charges against up to 57 people in connection with the Grenfell Tower fire that killed 72 people in June 2017.

The police files include possible cases of corporate manslaughter as investigators conclude their lengthy criminal investigation into the high-rise apartment building fire in west London. The blaze, which started on the fourth floor, spread rapidly up the exterior of the 24-story building due to flammable cladding.

The fire became one of the deadliest residential fires in British history and sparked widespread criticism of building safety regulations and oversight. Residents had repeatedly raised concerns about fire safety in the building prior to the incident.

The Crown Prosecution Service will now review the police files to determine whether formal charges should be brought against any of the individuals or organizations identified in the investigation. This process is expected to take several months as prosecutors evaluate the evidence.

The potential charges represent a significant development in the case, which has been the subject of both a public inquiry and a separate criminal investigation. Families of victims and survivors have long called for accountability from those they hold responsible for the tragedy.
