Police have arrested two men and three teens on suspicion of attempted murder after a Black Lives Matter activist was shot in the head at a party in Peckham.

Sasha Johnson, 27, is in a critical condition, having suffered “very serious” injuries after the shooting on Consort Road early on Sunday.

The force said officers based in Southwark and Lambeth 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 more males – 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 arrested on suspicion of affray and failing to stop for police later on Tuesday following a police pursuit of a car in Peckham.

They were all subsequently arrested on suspicion of attempted murder and remain in custody.

Searches are ongoing at two residential addresses in Peckham and in relation to the car that was stopped.

Police have said there is nothing to suggest that Ms Johnson was the subject of a targeted attack, stating that they are "not aware of any reports of threats made against her prior to the incident."

A man, believed to be in his 20s, also suffered a “superficial knife injury” in the incident.

He attended hospital and was discharged following treatment. No other injuries have been reported.

Detective Chief Inspector Richard Leonard from the Met’s Specialist Crime who leads the investigation said: “While the investigation remains in its early stages, these arrests show that progress is being made.

"However, I would continue to appeal to those who may hold information about the events that led to Sasha receiving her horrific injuries, or about those responsible, to do the right thing and come forward and speak to police.”
