Three children and a woman have died after a house fire in north-west London, with a man arrested on suspicion of murder.
Officers were called to assist the London Fire Brigade (LFB) at the scene of the blaze at the home in Tillett Close, Stonebridge, at 1.22am on Saturday.
A 43-year-old woman, a girl aged 15, and two boys aged eight and four died at the scene, the Metropolitan Police said. The force had initially incorrectly reported that the children were all boys.
Firefighters said the woman and one of the children were rescued from the second floor of the house but were declared dead by air ambulance crews.
The other two children were found inside the property as crews continued to tackle the blaze, LFB said, and were also declared dead at the scene.
Their next-of-kin have been informed.
A 41-year-old man was arrested at the scene on suspicion of murder and remains in custody.
Police have cordoned the street off and much of the house has been gutted by the fire.
Superintendent Steve Allen, from the Met’s local policing team in north-west London, said: “This is an extremely tragic incident and our thoughts are with everyone involved.
“Officers arrested a man at the scene and we continue to work alongside investigators from the London Fire Brigade to establish the cause of the fire.
“Emergency services will remain in Tillett Close throughout the day as these inquiries take place.”
Mayor of London Sir Sadiq Khan said in a post on X: “This is devastating news and my thoughts are with the family, friends and wider community of the four people who sadly have lost their lives.
“I remain in close contact with the London Fire Brigade and Metropolitan Police as they work to establish the cause of the fire and offer support to all those impacted.”
Mohamed Labidi, a 38-year-old teacher, who lives on Tillett Close, said he “can’t even look at the house”.
Speaking to the PA news agency, he said he knew the woman, and the four who died in the fire were “really good people”.
“We used to socialise together,” he said.
“I can’t even look at the house at the house right now.”
A person who lives next door to the house, who did not wish to be named, said: “It’s horrible, we saw people running outside.
“It’s hard to process. I only just moved in so it’s hard to think about it.”
Dawn Butler, the local Labour MP for Brent East, said in a post on X: “Devastated to see the fatal fire at homes in Tillett Close last night,” .
“My prayers are with the family and friends affected by this is a very sad tragedy.
