The Met Police has expressed its “sincere condolences” and is working to “how this dreadful incident happened” following the death of Sahara Salman.
Sahara, described by her mother as “an incredible little girl”, was killed in a gas explosion in Thornton Heath on Monday.
The blast demolished a terrace house in south London, injuring three others in the process.
Detective chief inspector Katherine Goodwin of the Met’s Specialist Crime, said on Thursday: “On behalf of the Metropolitan Police I would like to express my sincere condolences to all the family and friends of Sahara.
“This is a heart-breaking time for Sahara’s family, but I also fully understand how much distress this has caused the wider community.
“People will want to know how such a terrible thing has happened and everyone involved in the investigation is determined to provide those answers.”
Two other people – an 11-year-old boy and a 54-year-old woman - remain in hospital receiving treatment.
Sahara’s mother Sana Ahmad said her “world has been torn apart” by the tragedy and has also accused Southern Gas Networks of negligence. She said she contacted the supplier about a suspected leak on July 30. The company has expressed “deepest sympathies” but said it was inappropriate to comment while the police investigation continues.
Acting borough commander for the south west command unit, superintendent Richard Smith said: “The thoughts of all of us at the Metropolitan Police remain with Sahara’s family at this terrible time and my heart goes out to all those affected.
“I know the shock and anguish that is being felt in our local community, please be assured we are doing all we can to uncover how this dreadful incident happened.”
