A 17-year-old boy has been arrested on suspicion of conspiracy to commit grievous bodily harm following the stabbing in the back of a teenager.

Police and paramedics found the 17-year-old victim in Island Row, Limehouse, on Friday, September 21.

He was fighting for his life when he was taken to hospital but his condition is now stable, police said.

A 15-year-old boy had already been arrested on suspicion of attempted murder. Both boys are out on bail.

Det Sgt Lauren Brady, renewing an appeal for witnesses to come forward, said: “A young man has been seriously injured and we are working hard to piece together exactly what happened in the lead up to him being harmed.

“We know there were many people in the area when the victim was found injured. I am appealing for anyone with information to come forward.”
