Bearing down on violent crime on the streets of London continues to be a top priority for the Met. Teams across the city are working tirelessly - day and night – to identify and pursue offenders, help bring perpetrators to justice, take weapons off the street, support victims, engage and reassure the public, and keep our communities safe.
However, the police cannot solve this problem alone. The police, our partners and the public must work together to deal with knife crime and prevent further lives being lost. Communities have a vital role to play in tackling violent crime. We want to hear from anyone who may have information about people who may carry knives or firearms, or who are involved in organised drug crime and violence.
This information could save lives in the future. If you aren’t comfortable speaking directly to the police, please contact the independent charity Crimestoppers. They do not ask your name or trace your call.
If there are any young people who either have information about violence or knife crime, they can visit www.fearless.org where they can pass on information anonymously. Fearless is part of the Crimestoppers charity, and is also independent of the police.
