A 10-year-old boy was injured in a triple shooting in South London's Tulse Hill on Saturday as suspected gangland violence erupted in south London.

Shots were fired into a crowd of people at the Tulse Hill Estate at approximately 9pm after an argument was said to have broken out between two groups.

As well as the boy, two men, both aged 19, were rushed to hospital for treatment to gunshot wounds after they had been treated at the scene. Their condition is described as stable.

A 20-year-old man has since been arrested on suspicion of attempted murder and is currently in custody, but the Metropolitan Police Service is still appealing for witnesses who saw either the argument take place, or a Ford Fiesta or Ford Focus speeding away from the scene.

The estate had been milling with people enjoying the good weather and police believe someone could have seen something suspicious prior to the shooting.

Detective inspector Danny Gosling from Operation Trident, the Met's gang-tackling unit, 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 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."
