Life with minimum term of five years for teenager who killed Katie Rough, seven

A teenager who killed a seven-year-old girl in a park 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 16-year-old girl, who cannot be named and was 15 at the time, and then slashed with a Stanley knife in a park in York, in January.
