The London Fire Brigade has been interviewed under caution by police investigating the Grenfell Tower fire.
The fire service said it had been questioned as a corporate body as part of the Metropolitan Police's investigation into the blaze in West London in June 2017 which claimed 72 lives.
London Fire Commissioner Dany Cotton said she recognised that survivors and the bereaved "need answers" and that the fire service was committed to assisting investigators.
The Brigade said it was invited to give an interview as a corporate body, rather than an as individual, under the Health and Safety at Work etc Act 1974.
It said it wanted to make the information public as part of its "commitments to transparency" and efforts to help "in every way possible to prevent such a devastating fire from ever happening again".
In June, The Metropolitan Police revealed that 13 interviews had been carried out under caution by detectives leading the criminal investigation into the Grenfell fire.
Police said they would not be disclosing how many individuals the 13 interviews concerned and that more interviews were scheduled. The force said that just over 7,100 statements have been taken from witnesses, community and family members, emergency services personnel and others as part of its probe.
In March, police said no charges were likely to be brought for at least the next two years, arguing that it would be be "wrong" not to wait for the final report of the Grenfell Tower Inquiry.
The second phase of the inquiry is not due to start until early next year.
