An inquest ruled the death of a man at the hands of his schizophrenic grandson should have been prevented by police and health professionals.
John McGrath was 81 when he was stabbed at his home in Nottinghamshire in 2009 by Will Barnard. Police, who missed a chance to arrest him over a previous robbery, were accused of negligence and incompetence.
From the inquest, Damon Green reports:
