'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.
