A man has been arrested on suspicion of murder after a woman was found dead in east London.
Metropolitan Police officers were called to Earlham Grove in Newham just before midday on Boxing Day amid concerns over the welfare of a resident.
The body of a woman believed to be in her 20s was found at the address.
A 26-year-old man, thought to be known to the woman, was arrested at the scene.
Officers are working to establish her identity and inform her next of kin.
A post-mortem examination will be scheduled in due course, the force said.
A crime scene has been established.
The Met said the man remains in custody while homicide detectives from the Specialist Crime Command investigate.
