The suspect, who cannot be named because she is a minor, is charged with the murder of Katie Rough and possession of an offensive weapon.

Officers were called on Monday afternoon to an address in the Woodthorpe area of York, and said they found Katie with life-threatening injuries at a scene nearby. She was taken to hospital but died shortly after arriving there.

Local media reported she was found on a path leading to a playing field, and published pictures of a wooded area with a white forensics tent and a police cordon.
