The suicide of a young man "cancelled" by his peers at university has prompted a coroner to write to the government warning about "self-policing" among some students.
Alexander Rogers, 20, was in his third year studying at the University of Oxford's Corpus Christi College when he took his own life in January.
Oxfordshire coroner Nicholas Graham said Mr Rogers had been "ostracised" in the preceding days after a woman expressed discomfort about a sexual encounter between the pair.
In a Prevention of Future Deaths Report, the coroner urged the Department for Education to take action to stop similar deaths occurring related to the harmful effects of being socially ostracised.
