The Finnish National Bureau of Investigation is aware of the existence of approximately ninety criminal gangs with a total membership of around eight-hundred. There are several competing motorcycle gangs in Finland. A historic rivalry between the Hells Angels and Bandidos erupted in the Nordic Biker War in the 1990s. Other international biker gangs operating in the country include the Diablos, Outlaws, Red Devils and Satudarah, as well as Cannonball, a prominent domestic organisation.
