A coroner has recorded a suicide verdict after an 11-year-old boy was found hanged at his home.
Callum James, from Gainsborough, died at The Children's Hospital, in Sheffield, on September 6, last year, following an incident in Woodfield Road two days earlier.
The Gainsborough Charles Baines Community Primary School pupil had autism spectrum disorder and ADHD and had previously threatened to kill himself by jumping from a window.
An inquest in Lincoln heard the cause of death was hanging. Coroner Stuart Fisher expressed his sympathy to relatives.
A report commissioned by the Lincolnshire Safeguarding Children Board has recommended improvements in how young people can be supported and the county council has vowed to implement changes.
Chris Cook, chairman of LSCB, said: "The independent report makes it clear that this tragic death was neither predictable nor preventable.
"The sad truth is that no-one saw this coming. Not his teachers, his psychologist, his behaviour support staff, his autism outreach workers, his doctors, his nurse, his family action workers nor his parents."
