A hospital ward doctor has said it was “not essential” to tell his boss a psychiatric patient had been seen with marks on his neck and been overheard talking about ending his life with shoelaces, an inquest jury has heard. But after 32-year-old Peter Barnes was granted unescorted leave by the consultant in charge Dr Keith Rix he went missing from Cygnet Hospital in Wyke during an unsupervised cigarette break and a week later his body was found in its grounds. Yesterday Assistant Bradford Coroner Neil Cameron was summing up the evidence heard during the hearing into Mr Barnes's death in October 2011. The inquest continues.
