A woman has been stabbed to death in south London, police have said.
Emergency crews were called to Frith Road in Croydon shortly after 9am on Saturday and treated two injured people at the scene.
A woman in her 20s died at the scene, while a man in his 30s was taken to hospital with minor injuries.
He has since been arrested on suspicion of murder and remains in hospital.
A murder investigation has been launched, and detectives are in the early stages of establishing what happened, the Metropolitan Police said.
The force said initial enquiries suggest the incident began at a nearby address before escalating on to Frith Road.
Superintendent Mitch Carr, who leads local policing in Croydon, said the force wanted to “thank the members of the public, including a teenage boy, who bravely tried to help the victim”.
“This is a tragic incident where a young woman has lost her life and our thoughts are with her loved ones,” he added.
“We believe that this was an isolated incident, but understand that this news will shock the local community.”
