Neglect by one of England's largest mental health trusts contributed to the death of a boy, a coroner has ruled.
Chris Brennan, 15, died at Bethlem Royal Hospital, south London, in August 2014. He had been admitted six weeks before after incidents of self harming.
The coroner found a lack of a risk assessment and an up-to-date care plan had contributed to his death.
The number of self-harming incidents on the unit had "desensitised" staff to the dangers, said coroner Selina Lynch.
