A health trust has admitted an 18 year old who killed himself by lying in front of a train in Cambridgeshire had "slipped through the cracks" in the mental healthcare system.
Edward Mallen - a gifted student from Meldreth - died in February last year.
Today a coroner in Huntingdon recorded a verdict of suicide.
Edward's parents felt their son had been failed by Cambridge and Peterborough NHS Foundation Trust's mental health services after he was referred to them by his GP.
Since his death his father, Steve Mallen, has campaigned to help other teenagers with depression.
