A coroner has ruled neglect by medical staff contributed to the death of a man who died from dehydration while a patient in hospital.
Kane Gorny, who was 22, had been so desperate he called police to ask for a drink of water.
Officers were turned away when they arrived at St George's Hospital in Tooting.
Kane's mother, Rita Cronin, wants a corporate case brought against the hospital trust, which has apologised.
''Everybody along the way could have saved his life at one point,'' she added.
