A 15-year-old and two 16-year-old boys have been arrested on suspicion of murder after two teenagers were fatally stabbed just a mile apart in south-east London.
Another 16-year-old boy has been released on bail pending further inquiries.
Officers were called at about 5.10 pm on Saturday to reports people had been injured in Sewell Road, Abbey Wood, and Titmuss Avenue in Thamesmead.
Despite the attendance of police and paramedics, two 16-year-old boys were pronounced dead.
They have been named as Kearne Solanke and Charlie Bartolo.
The victims’ families are being supported by specialist officers, police said.
Following the announcement of the arrest, Det Chief Insp Kate Blackburn said in a statement: “This is a positive development in what is a complex and fast-moving investigation. Charlie and Kearne’s families have been informed.
“Our investigation is ongoing and we continue to appeal for the public’s help as we build a picture of what happened on Saturday night.
“If you have information, no matter how insignificant you think it may be, please come forward.”
