A murder investigation is underway after a teenager was shot and stabbed by a gang riding bikes, police said.
Scotland Yard said officers were called to reports of a group of people fighting on Vincent Road, Wood Green, just before 8.10pm on Friday night.
Police and ambulance crews attended the scene, on arrival two men, believed to be aged 19 and 20, were found with stab injuries and taken to hospital - where the teenager was pronounced dead shortly after 3am on Saturday.
The teenager had also suffered gunshot wounds.
Detective Chief Inspector Katherine Goodwin of the Met's Homicide and Major Crime Command, who is leading the investigation, said a gang who were riding bikes were armed with at least one firearm, knives and a samurai sword.
She said: "This murder took place at a busy time of night in a heavy footfall area.
"I know that there are people who either witnessed the incident or who can assist with filling in the gaps in the information we already have.
"Do you know who the attackers are? Did you see what happened leading up to or immediately following the murder? If you have information or footage of any of the events surrounding this incident we need to hear from you.
"My team has established that the attackers were armed with at least one firearm, knives and a samurai sword. Some, or possibly all, were riding bikes.
"I know that people may be reluctant or afraid to speak with police, but making a single call could help to remove dangerous, violent individuals from your area and all information provided will be treated in the strictest confidence.
"If you don't want to call police call the independent charity Crimestoppers - they won't even ask for your name, but please, if you have information, do make the call."
The road was closed and a police cordon was put in place while officers investigated, a spokesman said a damaged car was found at the scene.
Police said the man's next of kin have been informed and a post-mortem examination is due to take place "in due course".
The 20-year-old man's injuries are not thought to be life-threatening.
