An inquest has opened into the death of a Derbyshire schoolboy.
Jak Hikin, of Portland Street, New Houghton, died at King's Mill Hospital on February 19. He was 14-year-old.
His inquest opened at Chesterfield coroners' court on Tuesday.
Coroner Kathryn Hayes said: "The proposed cause of death has been given as 'compression to the neck'."
Ms Hayes said Jak - who had a diagnosis of autism spectrum disorder and ADHD - had regular contact with 'various healthcare and other services'.
She added: "That is something that's going to form part of my investigations. I'll need to investigate the role of those services."
Ms Hayes adjourned the inquest to a date yet to be fixed in order to carry out further investigations.
She told the court: "This is a very sad death.
"I can think of nothing worse than experiencing the death of a child.
"My condolences go to Jak's family and friends at this tragic time."
