Three men were injured following a shooting in north London in the latest incident of violence in the capital.
Two were believed to have suffered gunshot wounds after the incident at around 6pm on Saturday.
Officers found four men in Enfield as emergency services scrambled to the scene on Gordon Road after the shooting, Scotland Yard said.
Three were taken to a hospital in north London, a spokeswoman said. Their injuries are not believed to be life-threatening.
There have been no arrests and enquiries are ongoing.
Sotiri Dimpinoudis said witnesses to the shocking attack ran away to try and call police officers.
He told the Standard: "There was a brief panic during the shooting for 15 minutes, and people were running away to hide and called the cops.
"They [said] they saw the gunman running away."
A statement from the Metropolitan Police said: "Police were called to Gordon Road in Enfield at approximately 18:00hrs on Saturday, 17 November to reports of a shooting.
"Officers and the London Ambulance Service (LAS) attended.
"Four men were found at the scene. Three of the men were injured, including two believed to have suffered gunshot wounds. The three injured men were all taken to a north London hospital.
"None of the injuries are believed to be life-threatening.
"The Trident and Area Crime Command has been informed."
The shooting comes just hours after a mother, 75, was stabbed to death in south east London.
The elderly woman was stabbed in her own home, police said, and was described as neighbours as a "lovely lady".
The victim, named locally as 75-year-old Maureen Watkins, was found fatally injured at her home in Ethnard Road on Friday afternoon.
