Two men and two teenagers have been arrested on suspicion of attempted murder over the shooting of activist Sasha Johnson in Peckham, south London.
Johnson remains critically ill in hospital after being shot in the head after gunfire erupted at a party on Sunday night.
Police in the area stopped a 17-year-old boy on Tuesday and arrested him on suspicion of possession of an offensive weapon and possession with intent to supply class A drugs.
Their investigation led them to an address in Peckham where three others – an 18-year-old, a 19-year-old and a 28-year-old – were all arrested on suspicion of affray and possession with intent to supply class B drugs.
A fifth man, aged 25, was later arrested after failing to stop following a police pursuit of a car in Peckham.
They were all subsequently arrested on suspicion of attempted murder and remain in custody, the Metropolitan Police said.
Two homes in Peckham and the car from the chase are being searched, the force said.
“Around 3 am a group of four black males dressed in dark coloured clothing entered the garden of the property and discharged a firearm. They had left the scene before officers arrived.”
Commander Heydari went on to say that the police are “aware of Sasha’s involvement in the Black Lives Matter movement in the UK and I understand the concern this will cause to some communities – however, I wish to stress that at this time there is nothing to suggest Sasha was the victim of a targeted attack.”
Heydari said that the Metropolitan Police are not aware of any threats made against her prior to the shooting.
“I want to take this opportunity to reassure you that we are doing everything possible to identify those responsible and to bring them to justice,” the police commander said.
“Tackling violent crime on the streets of London is a top priority for the Met, and the people of London have a vital role to play in that,” she added.
