A thousand young, black men removed from Met gang violence prediction database

Exclusive: Sadiq Khan review into discriminatory' police matrix found 38% on list posed little or no risk

One thousand young, black men have been removed from an allegedly discriminatory gangs database used by police in London, after a review found they posed no or little risk of committing violence, the Guardian has learned.

The Metropolitan police's gang violence matrix contains the names and details of thousands of people who police say pose a risk of committing gang violence. It then gives them a score showing how likely they are to commit gang violence.
