A 15-year-old boy has died after suffering a single stab wound while cycling in north London.
Police were called just after 7.30pm on Friday to reports of a male collapsed in Caledonian Road, near the junction with Twyford Street, Islington.
Officers and paramedics from the London Ambulance Service attended but the boy was pronounced dead at the scene.
The victim has been named as Alan Cartwright. Next of kin are understood to have been informed.
Tributes and flowers have been left at the scene.
One mourner wrote: “So sad. Such a young life taken so young.”
Someone, writing on Twitter, said: “So sad that another Islington kid taken so soon. Thinking of your family at this sad time.”
Another added: “Devastated isn’t the word! RIP Alan.”
Former EastEnders actor Brooke Kinsella, whose 16-year-old brother Ben was knifed to death in north London in 2008, added: “Another young boy lost to knife crime, another family destroyed. Sickening, cowardly, senseless culture. Heart is weary #PutDownYourKnives”
Police said it is believed that the boy was riding north on Caledonian Road with friends before the incident happened.
The group was attacked close to the junction with Copenhagen Street by three males who had been walking south.
The victim suffered a stab wound but managed to continue cycling further up Caledonian Road before collapsing.
Two other members of the group had their bicycles stolen.
The suspects left the scene, making off south down Caledonian Road. No other injuries were reported.
Detectives say they are keeping an open mind as to the motive for the attack.
Investigating officer Detective Chief Inspector Chris Jones appealed for anyone who saw anything to get in touch.
He said: “Caledonian Road would have been very busy at the time of the incident and I would appeal to anyone who witnessed this attack, or may have any information as to who is responsible, to come forward and speak to police.”
