Violent biker gangs from Australia, Canada and the US have arrived in Europe prompting fears of a battle for organised crime markets throughout the continent.
Britain has been warned that turf wars could break out as 'Outlaw Motorcycle Gangs' fight for control over the drugs, weapons and human trafficking criminal markets.
The European Union's law enforcement agency has now warned of a repeat of the 1990s biker wars that left at least 11 dead.
Europol said the arrival of notorious gangs including Comancheros and Rebels from Australia, Rock Machine from Canada and Mongols and Vagos from the US has exacerbated tensions with established clubs.
It has informed police forces across the continent that established gangs are expandings and said there are already ongoing territorial battles with organised crime groups.
Football hooligans from Britain and the continent, as well as former military personnel, right-wing extremists and prison gangs are among those expected to be targeted for recruitment.
Europol said the four main groups - Outlaws, Hells Angels, Bandidos and Gremium MC - were all increasing their membership, particularly in north east and south east Europe.
