Police are appealing for witnesses after a double shooting in Crystal Palace on Wednesday which left two men suffering leg injuries.
Officers were called by the London Ambulance Service to reports of a firearm being discharged in Lunham Road, around 5:52pm.
The victims, aged 24 and 25 respectively, were rushed to hospital where their condition was deemed non life-threatening.
However, their injuries are said to be potentially “life-changing.”
Detectives believe that a group of people were filming a music video nearby when the suspects approached and shots were fired.
The motive is not currently known by officers, who say they are keeping an “open mind” but the possibility of the shooting being gang-related is being explored.
Officers from the Met’s Trident Crime and Area Command are leading the investigation.
Detective Inspector Ed Facer, who is leading the investigation, said: “At the time of this attack we believe there were approximately 40 people in the area watching or filming a music video being made.
“Understandably most of these people panicked and fled the scene; however we need to hear from them as a matter of urgency.
“The witnesses may have some mobile phone footage of the suspects that could really help our investigation and I would urge them to come forward to police to give an account of what they saw.”
There have been no arrests and enquiries are ongoing.
Witnesses who have not yet spoken with police are asked to call 101 quoting reference 5795/31OCT, tweet @MetCC or call Crimestoppers anonymously on 0800 555 111.
