A man has been arrested over the shooting dead of 17-year-old Tanesha Melbourne-Blake in Tottenham on Monday.
She was killed in north London on 2 April amid a recent rise in murders in the capital – most of them involving knives.
Police believe the shots were fired into a group of people from a car.
A 30-year-old was arrested in the east of the city on Friday morning on suspicion of murder. He remains in custody at a London police station.
Officers were called to Chalgrove Road at 9.35pm on Monday and found Tanesha with a gunshot wound.
Despite efforts to save her, she was pronounced dead at the scene just over an hour later.
Police say they have an open mind on the motive for the attack and are still trying to establish the car used in the murder, as well as the number of people in the car and in Tanesha’s group.
A 16-year-old, Amaan Shakoor, also died the same night after being shot in the face just a few miles away in Walthamstow.
Extra police have been put on the streets near where Tanesha was killed, and in the wider area.
Many of the 51 murder victims in the capital this year have been teenagers, with police concerned that social media is helping relatively minor disputes quickly escalate.
On Wednesday, Israel Ogunsola, 18, became another victim – stabbed Hackney and dying at the scene. Two 17-year-olds have been arrested.
Israel was Facebook friends with Tanesha Melbourne-Blake.
The violence continued on Thursday as a 13-year-old boy was among six teenagers taken to hospital after more incidents in London.
In a sign of the pressure on detectives, Scotland Yard has enlisted the support of City of London police to help cope with the number of cases.
Mayor of London Sadiq Khan has continued to attack the Government in light of the rising rate of violence.
He has blamed “the level of cuts” made to policing in the city, claiming that £700m of funding had been lost from the police budget since 2011.
Meanwhile, Metropolitan Police chief Cressida Dick has pledged to use “Al Capone” tactics in a bid to curb the number of murders and knife attacks in the capital.
She said a new task force of 120 officers would focus on the most violent gang members and individuals to take them off London’s streets “for any crime”.
US gangster Al Capone was jailed for tax evasion in the 1930s when traditional law enforcement methods failed.
