The bloody turf war between the Hells Angels and a rival motorcycle club called the Vagos, has also led to shoot outs in the neighbouring states of Nevada and Arizona. According to the US Justice Department both the Hells Angels and the Vagos are "outlaw" gangs involved in drug and weapons trafficking, extortion and money laundering. The current spate of bloodshed between them can be traced to a disagreement at a Stabucks in the beach town of Santa Cruz last year. A brawl in which some participants wielded ball-peen hammers erupted outside the coffee shop before police arrived and bikers scattered. That led to a gunfight in the northern Arizona town of Chino Valley which left five people wounded and 27 under arrest.
