LAS VEGAS, Nev. -- Authorities said they have busted up a racist white supremacist gang based in the Nevada state prison system.

Fourteen men are named in a federal racketeering indictment unsealed Thursday charging them with murder, extortion, drug dealing, fraud, identity theft and other violent crimes. The U.S. attorney's office and FBI say the men were members of the Aryan Warriors based in the prison system, but with tentacles in methamphetamine distribution in cities around the region.

The charges include allegations stemming from the stabbing death of a prison inmate in August 2001; assaults on two other inmates in 2004 and 2005; and the February beating of a person on the outside. They men are also accused of threatening and extorting money from inmate families, and stealing and using identification documents and credit cards.

Four of the accused were arrested Thursday morning in Las Vegas, another in Pahrump. The others are already in federal or state prisons. They are due Friday morning before a magistrate in U.S. District Court in Las Vegas.
