A teenager has been charged with the murder of 42-year-old Damien McLaughlin who died after suffering a stab wound to the heart.
Mr McLaughlin, of Cheshunt, was left with fatal injuries after an alleged attack in Enfield on Saturday afternoon.
Police, ambulances and London’s air ambulance were called to the scene on Exeter Road just after 1.30pm.
Paramedics fought to save Mr McLaughlin's life for over 45 minutes but he was pronounced dead at the scene at just after 2.15pm.
Police have charged a 17-year-old male from Tottenham with murder, possession of an offensive weapon and possession of cannabis.
He is due to appear in custody at Highbury Youth Court on Tuesday.
Police also arrested an 18-year-old man who remains in custody and a third person arrested - a man aged 21 - has been released from police custody.
DCI Larry Smith said: "We have spoken with a number of witnesses, but I am certain that there are other people who will have seen something of note but are yet to contact police.
"I am also aware that people may have recorded footage on mobile phones. I am urging any witnesses, or anyone with material that may assist the investigation, to make contact with police."
A post-mortem examination held at Haringey Mortuary established Mr McLaughlin's cause of death to be a stab wound to the heart.
Mr McLaughlin was one of three people killed in the capital's streets over the weekend.
In Battersea a 17-year-old cyclist was ambushed and fatally stabbed as he tried to flee a gang. And on Sunday a 60-year-old man was found dead from stab wounds at an address in Bow.
Anyone with information that may assist the investigation is asked to call the incident room on 020 8345 3985 or via 101. Alternatively, contact Crimestoppers anonymously on 0800 555 111.
