A 14-year-old boy has died after being shot in London, with three teenagers arrested on suspicion of murder.

The boy was killed in Woolwich, southeast London, the Metropolitan Police said.

Two teenage boys, aged 14 and 16, as well as an 18-year-old man were arrested on suspicion of murder on Thursday and are still being held in custody.

Police had previously referred to the victim as a man because they could not identify him but have now confirmed he was 14 years old.

Detective Chief Inspector Lucie Card, who is leading the investigation, said: "Our thoughts remain with the boy's family and loved ones.

"We are aware of the concern that this incident will cause the local community. We have already made three arrests and our investigation continues at pace. An increased police presence remains in the area.

"I would appeal for anyone who was in the area at the time, who has CCTV or dash cam footage of the incident or has information that could help my officers to come forward."

Officers were called to the scene in Lord Warwick Street, which is close to the Woolwich Ferry and Woolwich Dockyard train station, at around 3.40pm on Thursday.

The boy was pronounced dead at the scene and police said his family are being supported by specialist officers.

It is the second fatal shooting in the capital in less than a week.
