A pupil who was stabbed to death outside a school in Huddersfield has been named locally as 15-year-old Khayri Mclean.
Khayri died after being attacked near North Huddersfield Trust School shortly before 3pm on Wednesday, 21 September.

A crowdfunding page has been set up in his memory by Khayri's girlfriend, Shyana James, who laid flowers at the scene.
Writing on the Go Fund Me website, she said: "As u all no such a wonderful boy lost his life yesterday, he was only 15 years old [and] lived a good life."
Speaking to ITV News at the scene, Shyana's mother Sherrin said: "It's just heartbreaking. He was at my house every day. He was such a good boy and him and his girlfriend adored each other. They were inseparable, they were with each other all the time."
