The seeds of criminal and anti-social behaviour can be found in children as young as three, scientists have claimed.
More researchers believe that violent tendencies have a biological basis and that tests and brain imaging can pick them up in children.
They argue that, by predicting which children have the potential to be trouble, treatments could be introduced to keep them on the straight and narrow. If the tests are accurate enough then a form of screening could be introduced in the same way we test for some diseases.
The theories were put forward by two leading criminologists at the American Association for the Advancement of Science in Washington.
Prof Adrian Raine, a British criminologist, argued that abnormal physical brain make-up could be a cause of criminality, as well as helping to predict it.
