Police were called to Orchard Place, Tottenham, in Haringey, minutes from the Spurs stadium, just after midday on Saturday, June 18, to reports of a stabbing.
A 17-year-old boy was found at the scene, and died from his injuries.
He has been named locally as Ali Baygoren, from Tottenham.
Anti-knife crime protestors are planning a march from the murder scene in N17 to Edmonton Police Station this evening (Monday, June 20) at 7pm.
In a post shared online, organisers said: “No more deaths — let Ali Baygoren be the last!
“He has left behind a devastated family and a mother in pain, anguish and mourning.
“We no longer want to write obituaries for young boys who should have prospects and a fulfilled future to look forward to rather than a funeral or prison cell.”
They added: “The new Tottenham stadium is also visible from Ali’s bedroom — an arena reserved for visitors from more affluent areas and suburbs of London rather than Tottenham’s young locals who wouldn’t ‘dare to dream’ of being able to afford a ticket.
“We know that the problem is far beyond ‘taking knives off the streets’ of Tottenham, Haringey and other areas of London.
“It is time that the state and borough council began taking responsibility for its mismanagement, and completely transforms its policies to improve the living conditions of our communities and most importantly, keep our children alive.
“The children of Tottenham should have hope, access to good education, training and job opportunities, being able to plan for a better future, rather than struggling day-to-day to feed, clothe and protect themselves.
“As Ali’s family, we have lost our son and call upon everyone to make enough noise so that we are the last to go through this agony.
“We stand in solidarity with the hundreds of other families in London who have lost their children and with whom we share mutual heartache.
“Please join us and struggle in unity to demand convincing action against gang and knife crime in our community.”
A 15-year-old male was arrested the same day, and charged on Sunday, June 19, with murder.
He will appear in custody at Willesden Magistrates’ Court today, (Monday, June 20).
While two males aged 17 and 16 were arrested at the scene on suspicion of murder on Saturday, June 18, have both been bailed pending further enquiries.
A Met Police spokesperson said officers were called at 12.10pm, where they found Ali Baygoren having been fatally stabbed.
They said: “His next of kin have been informed. While formal identification awaits, police can confirm the deceased is Ali Baygoren from Tottenham.
“A post-mortem examination will be scheduled in due course.”
Homicide detectives with the force’s specialist crime command are investigating the incident.
