The Mongols are the "most violent and dangerous" motorcycle gang in America, according to police. Last year, a decade-long prosecution ended with a Californian jury finding the gang guilty of racketeering, conspiracy to murder, attempted murder and drug dealing. One of the gang's members said: "Being a Mongol promises you one of two things – death or prison." Now, the gang has started a chapter in New Zealand.
