Dutch judges on Wednesday banned the violent bikers gang the Bandidos and ordered all its chapters to close down, saying it posed a public threat.
"The Bandidos characterise themselves as lawless and use slogans that contain violent messages," the court in the Dutch city of Utrecht said in its ruling.
"The club has a culture in which carrying out serious violence is encouraged," it added, highlighting how patches crowing "Expect No Mercy" were handed out to members after bloody fights.
"A ban is therefore necessary in order to protect society."
The case had been brought by the Dutch prosecution service, which alleged the bikers were involved in drugs and arms trafficking as well as prostitution.
Founded in the United States in 1966, the Bandidos opened its first chapter in The Netherlands three years ago in the small southern city of Sittard.
Other Bandidos chapters then opened in the cities of Alkmaar, Utrecht and Nijmegen.
But the Bandidos presence raised the hackles of its bitter rivals the Hells Angels, and the southern Limburg province has witnessed a rise in violent crimes, including Molotov cocktails being thrown at members' homes and ugly public brawls.
Other countries such as Germany have already moved against the Bandidos, while in the United States gang leaders have been arrested and charged.
The Bandidos penetrated into Scandinavia in the 1990s, triggering a bloody war with the Hells Angels which lasted a decade.
Dutch justices have also tried in vain several times to outlaw the Hells Angels as a criminal organisation.
The court said there were more than 200 Bandidos chapters around the world with some 2,500 members.
