A man has been arrested in Britain after a woman was found beheaded in a back garden in north London, according to reports.
The victim was found at an address in Nightingale Road, Edmonton just after 1pm.
Scotland Yard gave few details but said that a man is in custody.
The force said: "Police were called to an address in Nightingale Road at 13.07pm today to reports of a stabbing incident. On arrival officers discovered a female collapsed in a garden area."
"A man has been detained and remains in custody. At this very early stage we are not in a position to give further details," they added.
Witnesses reported seeing a man running around the area as police arrived on the street.
Ambulance crews and an air ambulance were called, but it is understood the victim died at the scene.
In a statement, the Metropolitan Police added "At this early stage we have not yet spoken to the woman's next of kin. As such we are not prepared to comment on the exact nature of the woman's injuries or the type of weapon or weapons used."

The man (25) was arrested on suspicion of murder near by the scene of the incident. One officer was injured during the course of the arrest, believed to be suffering from a broken wrist.
A taser was also discharged by officers during the operation.
The police are not looking for anyone else in connection with the incident.
DCI John Sandlin, who is leading this investigation, said "This was a highly visible attack in broad daylight on a residential street. I can understand why this may cause people concern, however we are confident that we are not looking for anyone else at this stage."
"Whilst it is too early to speculate on what the motive behind this attack was I am confident, based on the information currently available to me, that it is not terrorist related."
"Local officers and specialist detectives are at the scene and will remain there for many hours to come. Specially trained family liaison officers will be deployed to support the family; we request that their privacy is respected at this very difficult time."
There is no suggestion that the killing had any terrorist motive.
Ricardo Kwiek was nearby when the police arrived on the scene.
