A vulnerable teenager died in a secure psychiatric hospital after workers were two-and-a-half minutes late checking in on her, an inquest was told.
Chelsea Blue Mooney, who suffered from anorexia and PTSD, was classified as a "high-risk patient" Cygnet Hospital in Sheffield where she required a high level of care.
She had made several attempts on her own life and was admitted to the facility under the Mental Health Act, with an employee required to look in on her every 10 minutes.
