Police have imposed a lockdown on an area around a home where four teenagers were found stabbed in a single incident.
The Met has imposed a Section 60 order on the area around Landor House, Southwark, after the incident which happened at 5.24pm this evening.
The order, under the Criminal Justice and Public Order Act 1994, allows officers to search for weapons within the restricted area – the order was originally introduced to combat football hooliganism.
Police had been called to reports of a stabbing outside Landor House, and arrived with paramedics.
Four males, all believed to be aged in their teens, were found suffering from stab wounds.
All of them were taken to South London hospitals and at this early stage police await updates on their conditions.
Six males have been arrested in connection with the incident and are all in custody at a South London police station.
A crime scene is in place and officers remain at the scene.
Superintendent Annmarie Cowley, of Southwark police, said: “This incident is in its very early stages and at present we cannot speculate on what the nature of it may be.
“What we can say for certain is if there needed to be an example of the utter senselessness of knife crime, then this is it; four males are in hospital, and at this stage we cannot say how serious their injuries are. It is beyond comprehension.
“I would like to offer my reassurance to the community that officers are responding robustly; we remain at the scene and have also requested additional resources from the Territorial Support Group and Violent Crime Taskforce to patrol the area.
“Additionally, a Section 60 has been authorised from 6.30pm to 9.30am on Friday, 17 August, providing officers with powers to deter any further potential trouble.
“I would urge anyone who witnessed this incident to call police and tell us what you saw; if you are concerned or worried about speaking to police, I can assure you your information would be treated in the strictest of confidence.
“If you are not a person who would speak to police but you know something, I would ask you to think of the families of those involved who tonight have a loved one in hospital. Please do the right thing and speak to us. Those responsible for this should not go unpunished.”
Any witnesses or anyone with information is asked to call police on 101 quoting CAD 5391/16 Aug.
