A woman whose son was stabbed to death in 2017 has appealed for witnesses after her two-year-old grandson was shot in the head in Harlesden.

Lillian Serunkuma’s grandson was one of four people, including his badly injured mother and two teenagers, who were shot in Energen Close on June 3 at just before 9.45pm.

Detectives believe a man carrying a handgun shot at one of the teenagers, then fired into a car containing the boy, his mother and the other teenage male.

The bullet missed a crucial artery in the toddler’s head by just 1mm and if it had been damaged, it would have killed the boy, doctors said.

In a plea for witnesses, Lillian said the person responsible “doesn’t deserve your protection or friendship”.

Lillian has experience of the suffering violent crime causes. In 2017 her 15-year-old son, Quamari Serunkuma-Barnes, was stabbed to death outside Capital City Academy, in Willesden.

Lillian said: “If you know the person responsible for this incident, you need to come forward and speak to the police. My grandson is two, he has never hurt anyone. The person who did this doesn’t deserve your protection or friendship. The gunman could clearly see that a woman and child were present in the car, and fired towards them without any regard for their safety, seriously hurting them both. My daughter has never hurt anyone and didn’t deserve to be shot multiple times protecting her child from harm.”
