Much of the violence described in the indictment involved clashes between the Mongols and their longtime rivals, the Hells Angels.
Mongols are accused of tangling with the Hells Angels at a Laughlin, Nev., casino in 2002, at a Toys for Tots motorcycle run in 2005 and at a Chuck E. Cheese in San Diego last year. Two Hells Angels and one Mongol were killed in the Nevada casino incident, the indictment alleges.
But the violence was not limited to disputes between warring gangs; some were motivated by race, but others appeared to be random acts.
Two Mongols, known as "Villain" and "Danger," are accused of beating a man to death with a pool cue in a Lancaster nightclub on Valentine's Day last year because he had been bad-mouthing the gang.
Another member is accused of shooting patrons of a Riverside bar and then trying to run them over in the parking lot, also in 2007.
A Mongol known as "Dago Bull" told an undercover agent that he and two fellow Mongols tortured a man in 2006 by breaking his knuckles with pliers and one of his knees with a metal pipe.
Another member boasted of having beaten a man so badly that he knocked out a tooth, which he kept taped to his microwave as a souvenir.
A Mongol known as "Monster" and two other members are accused of beating a black man at a Hollywood bar in 2006 while shouting racial slurs, the indictment states.
Other members allegedly beat and repeatedly stabbed a Latina whom they saw in the company of a black man.
Some of the defendants face potential life sentences in federal prison if convicted.
Most made their initial court appearances Tuesday. Others were expected to appear before federal magistrates today.
O'Brien said the restraining order he is seeking would prohibit the Mongols from wearing anything with that name, which is typically accompanied by an insignia of a pony-tailed, Genghis Khan-like figure riding a chopper.
Anyone caught wearing Mongols apparel could have it seized by police on the spot, he said.
