A woman has been arrested and detained in a secure mental unit after a four-year-old girl was stabbed to death, Scotland Yard said.
Officers found the child’s body inside a flat on the Chatsworth Estate in Clapton, east London, on Thursday.
A 36-year-old woman, believed to be girl’s mother, was arrested at the scene on suspicion of murder. She has since been sectioned under the Mental Health Act and remains in a secure unit.
Police were called to reports of a stabbing shortly after 3pm.
An ambulance was sent to the flat, but the girl was pronounced dead at the scene. Police said next of kin have been informed, but are awaiting formal identification.
A post-mortem examination will take place on Saturday at Poplar mortuary in east London.
The Metropolitan Police’s child abuse investigation command is leading the murder inquiry.
