Members of a white supremacist prison gang are alleged to have murdered, maimed and kidnapped rival inmates, as well as conspired to sell meth in a litany of crimes dating back to 2005, an indictment filed in Oklahoma claims.

Unsealed on Wednesday, the Tulsa grand jury filed indictment names 18 members of the 'whites-only' prison gang, the Universal Aryan Brotherhood, as culprits.

The Neo-Nazi group are said to have hundreds of members operating both inside and outside of prison facilities across Oklahoma.

According to the lawsuit, the brotherhood members orchestrated their enterprise's plans through the use of cellphones illegally smuggled into various prisons across the state.

The indictment alleges the gang members - and 36 unnamed co-conspirators - trafficked methamphetamine and marijuana, assaulted and kidnapped people to intimidate them, killed rivals and murdered at least one carjacking victim.

Michael Eldon Clinton (left), 41 and Randy Lee Seaton (right), 44, were two of four members who pleaded not guilty to the multitude of charges on Tuesday

Brandy Simmons also pleaded not guilty. The trio, along with 15 others, face charges relating to a racketeering enterprise conspiring to commit murder, to kidnap and to distribute drugs

Michael Eldon Clinton, 41; Randy Lee Seaton, 44; Brandy Michelle Simmons, 41; and Richard Wade Young, 48, were all arrested in relation to the indictment on Tuesday, pleading not guilty.

The indictment doesn't indicate if the charges are related to drug charges filed last week against alleged members of a white supremacist gang in Arkansas.

It does, however, list a series of 'overt acts' that grand jurors believe come as part of a racketeering conspiracy, spanning a 14-year period.

Among the charges is an allegation relating to the stabbing of Donald Jones, who was murdered in the privately-run Cimarron Correctional Facility in 2005.

Johnny 'JJ' Jameson is said to have carried out the killing with two accomplices under the instruction of UAB leaders, who wanted to retaliate against black inmates for the killing of Adam Lippert, a UAB member.

In 2013, Christopher Baldwin is alleged to have ordered five members to kidnap and wound an ousted UAB member and carve off his tattoo of the brotherhood's symbol from his body.

Additional charges include the murder of two Irish Mob members, orchestrated beatings and retaliation stabbings.

The Universal Aryan Brotherhood is also accused of conspiring to distribute more than 500 pounds of methamphetamine over prison lines. Two of the group are alleged to have attempted to smuggle over 30 pounds of meth in a single go (pictured: file photo shows 39lbs of methamphetamine)

The Tulsa grand jury also claim one UAB member is responsible for the carjacking and fatal shooting of a student at the University of Tulsa.

Billy Hamons is alleged to have stolen firearms in a home invasion, which he later used to kill student Sufend He, during an attempting carjacking in Tulsa.

15 of the 18 members outlined in the lawsuit are charged with conspiracy to participate in a racketeering enterprise.

In addition, all 18 of those named allegedly conspired to distribute 500 grams or more of methamphetamine, across prison walls.

In one instance, Lisa Lara and Robert Zeilder have been accused of transporting more than 30 pounds of meth for the UAB in 2013.

More details of the indictment will be revealed by the US Attorney's Office, following a conference on Thursday afternoon.
