Three teenagers have been arrested on suspicion of murder after a 14-year-old boy was fatally shot in Woolwich, south-east London.

The Metropolitan police said officers received reports of a shooting on Lord Warwick Street, Woolwich, at about 3.40pm on Thursday.

The force confirmed that the victim was 14-year-old Eghosa Ogbebor. The three people arrested are two boys aged 14 and 16 and an 18-year-old man.

DCI Lucie Card said: “Our thoughts remain with Eghosa’s family and loved ones. They are being supported by specially trained officers and have asked for privacy at this difficult time.

“I know the concern this has caused within Woolwich and the wider community, particularly considering Eghosa’s young age. We have an increased police presence around the area. While we have made three arrests, our investigation continues and I would urge anyone with any information to come forward and speak to officers.”

There is absolutely no place for this heartbreaking violence. I remain in close contact with the Met who have been working around the clock. Arrests have already been made and an investigation is under way.”

The shooting took place on a residential street close to Woolwich Dockyard train station. Anyone with information or footage can call police on 101 or Crimestoppers, anonymously, on 0800 555 111.
