Three men have been arrested on suspicion of attempted murder after a 15-year-old boy was stabbed in north London.
The victim was found lying in the road in a critical condition after being stabbed several times on the Broadwater Farm estate in Tottenham at around 11.14am on Friday.

“If you know anything about the circumstances surrounding the incident or if you witnessed it, please do come forward.
“I would also appeal to the members of the public who valiantly administered crucial first aid to the victim to come forward to my investigation team.
