A two-year-old boy is in a coma after being shot in the head by a motorbike-riding gunman in north-west London, according to a worried relative.

Two teenage boys were also shot alongside the baby’s mother, a 27-year-old woman, who was shot eight times including in the chest, arm, and leg said the relative. Police said the three adults’ injuries are ‘not life-threatening.’

The shooting happened at around 9.45 pm yesterday evening on a residential road in Harlesden, north-west London, police said.

The gunman first shot the teenage boys, 18-year-old Juan Young-sam and 19-year-old Rynell Seaton, according to the relative.

He then shot the woman, 27-year-old Piera Hutton, and her two-year-old boy, with a handgun as she attempted to flee the shooting.

Piera Hutton called a family member from the scene to ask for help, explaining what had happened, according to the family.

The relative, a teenager who did not want to be named for her family’s safety, said:

“Rynell and Juane were walking with Lillian, Piera’s mum, back to her house, when the boys just came and started shooting.

“They tried to shoot Rynell in the neck, but he ducked and they shot him in the arm. Then Juane tried to run off but they shot him in the back and leg.”

She added:

“Then I think Piera was in the car near her house trying to run with her baby.

“They shot her eight times in the chest, leg, backside and arm. Then they went to the baby, close range, and shot him in the head. The bullet went straight through the other side. Piera called my grandma for help and she rushed over there and saw all of them on the floor, Juan, Rynell, Piera and the baby, going into the ambulances.”
