A woman has been arrested after two sets of twin boys, aged three and four, died in a devastating house fire in south London.
The woman (27) is being held on suspicion of child neglect, the Metropolitan Police said.
Fire crews were called to a mid-terrace house in Collingwood Road, Sutton, shortly before 7pm on Thursday and found a “very well-developed” blaze, with the four boys inside, said Richard Mills, deputy commissioner of the London Fire Brigade.
He told reporters at the scene on Friday: “I can confirm that they are two sets of twins, ages four and ages three.”
Asked if anyone else was in the home, he said: “On arrival there were four children in the house.”
Scotland Yard said the boys were all related.
They were treated at the scene before being taken to two south London hospitals where they were pronounced dead.
In a statement on Friday morning, the force confirmed the arrest and said the woman remains in police custody.
Mr Mills said firefighters in breathing apparatus entered the home, removed the four children and gave them CPR. The fire was under control by 8.36pm and the cause is under investigation.
Speaking of the firefighters involved, he said: “Entering a building and rescuing life is always a very difficult place to be. The age of the children, the fact they are so young, will have a profound impact on them.”
Crews who attended are receiving counselling, he added.
London Fire Commissioner Andy Roe also earlier said the children’s deaths had “left everyone numb with profound sadness”.
Floral tributes were being laid outside the police cordon on Collingwood Road on Friday morning, with a message on one bouquet reading: “Sleep well. Love Grandad.” – PA
