A teenager who killed a seven-year-old girl in a park in York has been given a life sentence and ordered to be detained for a minimum of five years by a judge who said it was a "truly exceptional case".
Katie Rough died after she was smothered by the girl, who was 15-years-old at the time. She cannot be named for legal reasons.
Seven-year-old Katie was found with severe lacerations to her neck and chest on a playing field in York in January 2017 and died later in hospital.
The defendant, who is now 16, admitted manslaughter due to diminished responsibility at a previous hearing, appeared by video-link at Leeds Crown Court as Katie's family looked on from the jury box.
