Murders committed by mentally ill people are not on the increase, despite popular belief, psychiatrists have claimed.
People who have drunk too much or taken drugs are more likely to kill someone, they said.
The finding comes in a study by the Royal College of Psychiatrists (RCPsych), which found a steady decline in the proportion of murders committed by people with mental disorders between 1957 and 1995.
It concludes that people are more likely to win the National Lottery jackpot [14,000,000 - 1] than to die at the hand of a stranger with a mental illness.
It also says the finding proves that the care in the community scheme is not a "dangerous experiment" and should not be reversed.
However, high-profile murder cases involving schizophrenic patients in community care have led the public to fear attacks from mentally ill people and the government to review the scheme.
