The reputed leader of a white supremacist gang and another inmate escaped an Arkansas jail on Wednesday — and remained on the run early Thursday, authorities said.

Wesley Gullett, 30, and Christopher Sanderson, 34, were discovered missing early Wednesday at the Jefferson County Jail, where Gullett was being held on attempted murder and racketeering charges in a methamphetamine drug trafficking ring operated by the New Aryan Empire.

Gullett was identified as the gang’s leader in February as federal prosecutors charged him and 53 others in a wide-ranging indictment, alleging its associates committed attempted murder, kidnapping and aggravated assaults to continue their operation.

The gang — which formed in 1990 in an Arkansas jail with a goal to “preserve the Caucasian race” — is believed to have about 5,000 members, the Arkansas Democrat-Gazette reports.

The pair escaped after padding their bunks to make it seem as if they were still inside their cells, before somehow getting to the roof of the building and then beyond a fence along its perimeter, Jefferson County Sheriff Lafayette Woods Jr. told the newspaper.

“If they don’t see movement, they are required to physically confirm that the inmate is there,” Woods said of the jail staffers. “In this case, that did not happen. They did the checks, but they did not go in physically to confirm that the inmates were indeed in their bunks.”

Sanderson, who has no apparent ties to Gullett, was in custody on federal gun and drug charges. Both men should be considered armed and dangerous, according to the US Marshals Service.

The US Marshals are offering rewards of $10,000 and $5,000 for information leading to the arrest of Gullet and Sanderson, respectively.
