A 13-year-old boy shot in north-west London was an innocent bystander, according to police.
The boy was one of five people shot in the capital over a 24-hour period.
He suffered pellet wounds as he walked with his parents in Wealdstone High Street at about 13:15 BST on Sunday.
Police believe two others were shot with an air gun, including a 15-year old boy who is in hospital with a head injury. A third victim was hit in the arm, but has not come forward.
Officers described the attack which left the 13-year-old injured "callous, reckless and brazen".
Wayne Bent, who was part of a group who helped treat the boy until an ambulance arrived, said: "There was lots of blood.
"The main area was the back of the head - it was just constantly bleeding."
The teenager was treated in hospital and has now been discharged.
Local resident Jonathan Smith said he had "heard gunshot before" in the area.
He said: "I sometimes feel a little bit unsafe living around here. There's quite of lot of youths hanging around."
Officers from the Met Police's gang crime unit believe the missing man and the 15-year-old were the intended targets of the attack.
A man in his 30s was arrested on Sunday and has been released under investigation.
In separate attacks, 17-year-old Rhyhiem Ainsworth Barton was shot dead in Southwark, and a 22-year-old suffered non life-threatening wounds in a shooting in New Cross Road, Lewisham.
His mother, Pretana Morgan, has called for an end to the violence in London.
"Let my son be the last and be an example to everyone. Just let it stop," she said.
Mayor of London Sadiq Khan said: "This violent crime in London and across our country is simply unacceptable. It cannot be tolerated."
