Detectives investigating two separate shootings in Tottenham and Walthamstow are appealing for the public's help.
On Monday, 2 April a 17-year-old girl died after she was shot in Tottenham and a 16-year-old boy remains in a critical condition after he was found suffering from gunshot injuries in Walthamstow.
There is no evidence at this stage to suggest the incidents are linked. The fatal shooting in Tottenham is being investigated by the Homicide and Major Crime Command whilst the shooting in Walthamstow is being investigated by detectives from the Trident and Area Crime Command.
In Haringey police were called to Chalgrove road, N17 at 21:35hrs to reports of a shooting.
Officers attended along with the London Ambulance Service and found the teenage girl suffering from a gunshot wound.
Despite the best efforts of the emergency services she was pronounced dead at the scene at 22:43 hours.
Whilst her next of kin have been informed she has yet to be formally identified. A post-mortem examination is taking place today, Tuesday 3 April.
At this early stage it is believed shots were fired from a vehicle into a group of people, hitting the girl. At this stage detectives are working to establish the type of car and how many people were both in the vehicle and within the group shot at.
They are keeping an open mind about the motive for the attack.
In a separate incident in Walthamstow, police were called at approximately 22:00hrs to Markhouse road, E17 to reports of shots fired.
The emergency services attended and two teenage boys - aged 16 (Victim 1) and 15 (Victim 2) were found injured.
Victim 1 was found suffering from gunshot injuries and victim 2 with stab injuries. They were both taken to an east London hospital.
Victim 1 remains in a critical condition and victim 2 has life-changing injuries but not life-threatening.
There have been no arrests at this stage in relation to either incident.
Detective Chief Superintendent Richard Wood, in charge of the Homicide and Major Crime Command said: "Once again this weekend violent crime and the murder of young people on our streets has hit the headlines, and quite rightly.
"Today there are families and loved ones struggling to come to terms with the loss of their children and best friends.
"We are concerned about the number of people being killed on our streets, and 2018 has shown the reality that more young people are prepared to turn to more serious violence more quickly.
"Our homicide detectives are working incredibly hard to do all they can to identify and catch those responsible. Of the 48 murders this year, there have been 76 arrests and 47 charges.
"Whilst the reasons for the rise in violence, being seen across the country, are many and complex, the role of the police is clear. The absolute priority for the Met is to bear down on violent crime in all its forms, but especially knife and gang crime. Right now our officers are on the streets and will make more arrests for violence, take more knives off the streets and prevent violence.
"We are making progress in tackling knife crime, through Operation Sceptre and Trident, and our efforts will continue. However, the reality is we cannot police our way out of this problem alone. All of London’s agencies and every Londoner must be part of a long term effort to turn our young people away from knives.
"Our intelligence led operations, use of stop and search, proactive targeting of specialist teams into areas seeing high levels of violence will all continue."
Chief Superintendent Helen Millichap, Haringey Borough, said of the murder: “This crime is absolutely devastating and leaves a loving family suffering unimaginable pain. It is also very frightening for the community. Detectives from the Homicide and Major Crime Command are leading the investigation and continue to work with the local command to identify and arrest those responsible. We are working hard to prevent further violence and keep people safe, by making sure extra officers are deployed to Haringey and to this area in particular. They will be both highly visible and in plain clothes - carrying out a range of intelligence-led operations and patrols.
"The use of Section 60, the intelligence led pre-authorised power to stop and search, has been continually reviewed and will be deployed for as long as we have the intelligence that it is necessary. Local officers are being supported by specialist teams.
"I want all of us in Haringey to tackle this problem together. You may see and hear things that will help us prevent danger. If you or someone you know has information about young people carrying weapons please tell us, we will take action.”
