Horror CCTV shows the chilling moment a gang of attackers brandished machetes before the fatal stabbing of a 19-year-old father.
Tyrell Graham, 18, and Sheareem Cookhorn, 21, were found guilty of killing Mr Gabbidon-Lynck on Friday as well as attempted murder of a second man, 20, who suffered life threatening injuries in the attack.
Three 17-year-olds were also convicted of murder as well as grievous bodily harm with intent.
The jury heard the group had been calculated in their plan to cause serious injury on the night of February 22.
The gang of seven males, including the five defendants and two unknown individuals, carried at least five knives, including a machete and a small sword, a handgun and a shotgun.
On the night before, they had parked a silver Peugeot 307 on the Broadwater Farm Estate, which would become their meeting point before and after the attack.
They then set off on bicycles towards Wood Green at around 7pm to search for suspected rival gang members who may also have been out that evening.
On approaching Lordship Lane near the Vue cinema complex, the group first sighted the victims who themselves were with two others.
The gang immediately dropped their bicycles and produced knives and the firearm. Cookhorn fired shots at the victims.
These missed the target and one bullet was later recovered in a nearby shop, after travelling through the open door and narrowly missing customers and staff.
The victims’ group prepared for fight but changed their minds and decided to flee when Cookhorn fired his handgun.
The defendants began to chase them, brandishing their weapons in plain sight.
During the pursuit the victims split up into two pairs. Mr Gabbidon-Lynck and the second victim rain back towards their parked car while the other two escaped unharmed.
The defendants went back after the two victims, who had subsequently run off in different directions.
They soon caught up with the 20-year-old victim, surrounded him, and viciously began to attack, stabbing him eight times and shooting him once in the buttock.
However, their attack was interrupted when Mr Gabbidon-Lynck - who had managed to return to his parked car - drove towards the defendants in a failed attempt to frighten them off.
The gang then began to strike the car windows and windscreen with their weapons and Mr Gabbidon-Lynck tried to escape by reversing away.
However, he was cornered after backing into several parked cars on Vincent Road, so abandoned the vehicle and into a hairdresser that was just across the road hoping to barricade himself inside.
The gang burst into the shop and launched a stabbing spree.
Police were called to the scene at 20.09pm. The London Ambulance Service’s paramedics immediately began to attend to both the victims and transported them to hospital.
Despite the efforts of doctors, Mr Gabbidon-Lynck was pronounced dead shortly after 3am on Saturday, 23 February.
Detective Chief Inspector Simon Stancombe, of Specialist Crime North, said: “So desperate were the defendants to continue their petty postcode rivalry, the gang launched their gun and knife attack outside a busy cinema and several restaurants packed with people and children enjoying their Friday night.
“Having chased down Kamali and his friend like a pack of animals they set about them with a ferocity I have rarely seen.
"Not content with the damage they had caused that night they then boasted about their murderous exploits in amateurish drill videos.
“In truth, there are no winners, no bragging rights or anything to be proud of. One man is dead, another has life changing injuries, a family is utterly bereft and five young men will spend the best days of their lives behind bars."
