Police are appealing for information after a shooting in Tulse Hill which left three men injured.
Officers and paramedics were called at about 9pm on Saturday, 17 May, to reports of shots fired in the Tulse Hill Estate.
Three men - two aged 19 and one 20-years-old - were taken to a south London hospital for treatment to gunshot wounds.
All three are in a stable condition.
Officers from the Trident Gang Crime Command investigate.
It is believed an altercation took place between two groups before shots were fired into a large crowd of people leaving the three men injured.
Police are appealing to witnesses to come forward with information or anyone who may have seen the lead up to the shooting.
They are particularly keen to speak to anyone who may have seen an argument taking place between the two groups and a car - either a Ford Fiesta or Ford Focus - speeding away from the scene.
Officers are keeping an open mind into whether this is gang related.
Detective Inspector Danny Gosling, of the Trident Gang Crime Command, said: "When the shooting happened, lots of people would have been outside enjoying the good weather and may have witnessed something.
"We would like to hear from anyone who may have seen anything suspicious before and after the shooting. I'm keen to speak with anyone who may have seen either a Ford Focus or Ford Fiesta speeding away from the area of Leander Road or the Tulse Hill Estate at around 2100hrs on Saturday night. I would appeal to those people to contact us immediately as they may hold key information.
"I have no doubt that this could have resulted in graver injuries as the shots were fired in the direction of the group.
"I would like to reassure the public and residents in the area that we are doing all we can to find those responsible for this incident and bring them to justice."
Yesterday officers arrested a 20-year-old man on suspicion of attempted murder and is in custody at a south London police station.
