The teenager was discovered with a number of stab wounds in Matheson Lang House in Baylis Road near Waterloo Station in London, Scotland Yard said.

A London Ambulance Service spokesman said: "We were called at approximately 3.45pm to reports of an incident at an address on Baylis Road, SE1.

"We sent a fast response car, an ambulance, the air ambulance and an officer to the scene, the first of which arrived in under four minutes.

The girl is the 16th teenager to be killed violently in London so far this year.
