<P> On August 12, 2007, Hells Angel Gerry Tobin, a Canadian living in Mottingham, London, was shot dead on the M40 motorway while returning from the Bulldog Bash festival held near Long Marston, Warwickshire . He was singled out at random by members of the Outlaws . In November 2008, seven members of the Warwickshire chapter, were convicted of his murder and sentenced to life imprisonment . </P> <P> On January 20, 2008, there was a brawl between up to 30 of the rival clubs at Birmingham International Airport . Police recovered various weapons including knuckledusters, hammers and a meat cleaver . Four Outlaw members and three Hells Angels were imprisoned for six years each . Increased security at the court, for the period of the trial, cost around £ 1 million . </P> <P> In April 2000 full - patch member Jan Wouters was killed by Outlaw André Renard in the presence of two other Outlaws on the club's domain in Mechelen . All three members were given life sentences for the murder of their fellow Outlaw . Among them was the brother - in - law of the victim . According to the three convicted Outlaws the murder took place after an argument escalated . Upon escalation Wouters supposedly aimed a gun at his brother - in - law after which he himself was killed . It was largely believed that the murder was not the result of an escalated discussion, but rather an execution approved by the club's hierarchy . </P> <P> On October 4, 2009 several Hells Angels and allied Red Devils performed a raid on an Outlaw MC clubhouse in Kortrijk . Shots were fired and three Outlaws were wounded before the Hells Angels and their Red Devils comrades fled the scene . The incident occurred after members of the Outlaws MC supposedly pushed over a motorcycle belonging to Red Devils MC president Johan F. in Moeskroen . The raid is also thought to be a part of a territorial dispute between the Hells Angels and the Red Devils on one side and the Outlaws on the other . Several months before the raid, on the 24th of July 2009, members of the Red Devils and Hells Angels already retaliated by setting fire to motorcycles outside an Outlaw clubhouse . Eventually six Hells Angels and two Red Devils were convicted for attempted murder and given sentences from five to twenty years in prison . </P>
