Boys who carry the gene are likely to be dangerous, violent and carry weapons, according to the research.

The gene affects levels of the brain chemicals dopamine and serotonin – which affect behaviour and mood.

But the gene defect has no effect on girls, it emerged.



Scientists have previously linked the gene to anti-social behaviour but have not been able to confirm the link with gangs and guns until now.
