Hells Angels on a revenge mission ambushed rival bikers and stabbed one twice in the chest as stunned people looked on.
The surprise attack in Findon, Worthing, left the stabbed biker fighting for his life and two more injured.
Three attackers have been jailed after they admitted the assaults on a group of Vikings bikers on the A24 on October 8, 2022.
Last week, Lewes Crown Court sitting in Hove heard the Vikings took jackets from prospective Hells Angels members at services in Surrey earlier in the day.
The Hells Angels decided to get revenge on their rivals, His Honour Judge Jeremy Gold KC said.
They drove to Portsmouth where they ransacked an empty Vikings clubhouse before hunting their rivals down to a pub in Worthing.
Judge Gold said wrecking the clubhouse was not regarded as “sufficient retribution”.
After finding the Vikings meeting, the Hells Angels waited until a smaller group had broken off before carrying out their revenge assault.
Hells Angels vehicles, including a taxi driven by a biker, pulled up in front of the group of Vikings on bikes.
Three bikers managed to flee.
Three others were set upon by between ten and twelve Hells Angels, the court heard.
One of the Vikings was stabbed twice in the chest by Hells Angel Callum Shaw.
Shaw, 27, from Watford was jailed for a total of 17 years for stabbing Jack Worsfold.
Prosecutor Amy Packham told the court Shaw had been a “full patch” member of the Windsor chapter of Hells Angels for about five years.
He had travelled to the clubhouse in Portsmouth to get retribution for the disrespect, then on to Worthing where they found the Vikings holding a meeting in a pub.
Ms Packham said: "There were a large number of motorcycles parked outside the pub.
"There was no effort to confront them at that point. When the meeting broke up, a group of Vikings on motorcycles were followed by the three Hells Angels vehicles which culminated in the incident on the A24.
"Shaw was identified last as the main person involved in the attack and remanded.
"This was a surprise attack on a group of six Vikings on motorcycles. Three of them managed to drive off. Three did not. They were all attacked."
Shaw chased Mr Worsfold and stabbed him twice, Ms Packham said.
A number of onlookers including diners at a restaurant on the A24 rang 999.
None of the Vikings or Hells Angels cooperated with police and none gave statements.
But the attack was caught on camera.
"Shaw jumps out of the van," Ms Packham said. "The Viking runs across the road, chased by Shaw. He was stabbed a number of times."
Shaw was joined by two more Hells Angels.
Barry Brown, 41, from Calow, Derbyshire, and Daniel Kent, 28, from Bushey, Hertfordshire joined in the assault, punching, kicking and stamping on Mr Worsfold.
His head was protected by his motorcycle helmet.
"Brown stamping, Kent with the baton and Shaw stabbing," Ms Packham said.
Mr Worsfold suffered rib fractures, a collapsed lung and lost a significant amount of blood.
Paramedics at the scene were concerned for his life, the court heard.
"He was lucky," Ms Packham said.
Taxi driver Brown was jailed for three years for ABH and violent disorder.
Kent was jailed for three years for ABH, violent disorder and another 12 months to be served consecutively for burglary at the Vikings clubhouse in Portsmouth.
Sentencing them, Judge Gold said all three men knew exactly what they were doing and went into it with their eyes wide open.
He said: "This started as a minor dispute. Two prospective members of the Hells Angels were disrespected by Vikings members. A decision was taken to wreak revenge.
"Breaking into their HQ in Portsmouth was not regarded as being sufficient retribution. You located them and followed a small group.
"They were attacked by a larger group of which you were members."
