Scotland Yard said that the investigation team had grown to 220 people. Deputy Assistant Commissioner Kevin Southworth said: 鈥淭he Grenfell Tower fire remains one of the most complex investigations ever undertaken by any UK law enforcement agency."
The report explained some of the reasons why survivors and the bereaved have been waiting so long, with the police only now able to pledge that the Crown Prosecution Service would have the evidence needed to make charging decisions a decade after the fire.
The investigation has looked at the role of 15,000 individuals and 700 organisations. The police now suspect 57 individuals and 20 organisations of criminal offences, including gross negligence manslaughter, misconduct in public office, fraud and health and safety matters.
Investigators have gathered 165 million electronic files, taken 14,400 statements, and examined more than 27,000 exhibits including cladding, insulation, doors, windows and other parts of the building.
The Met has submitted 15 of 20 files to the CPS, and 10 of 14 overarching evidence files are complete. The length of summary reports to the CPS exceeds 2.2 million words: a little under twice as long as Marcel Proust's In Search of Lost Time.
