Police have launched a murder probe after a 35-year-old woman died in Ilford on Monday.
Officers were called at about 7.40am to reports of a disturbance in Applegarth Drive, a residential street.
They found the woman suffering an abdominal injury. Police said it was unclear how she sustained this. She was taken to hospital but died about three hours later.
A 50-year-old man was arrested at the scene on suspicion of attempted murder. He was taken to a police station and subsequently arrested on suspicion of murder.
He remained in custody on Monday evening.
Police said the pair were known to each other, and that no one else was being sought for the investigation.
DCI Gary Holmes, of the Met’s homicide and major crime command, said: "This is a tragic incident and our sympathies are with the loved ones and friends of the victim.
"I am appealing for any witnesses who were in the area of Applegarth Drive from the evening of November 11 to the morning of November 12 to please contact us with any information they might have, however small. It could prove vital to our ongoing enquiry."
Anyone with information can call 0208 345 1570 or Crimestoppers anonymously on 0800 555 111.
