Authorities say they’ve captured the leader of a white supremacist gang who escaped from an Arkansas jail earlier this week.

A spokeswoman for the U.S. attorney’s office in eastern Arkansas says Wesley Gullett was captured Thursday in Pope County in western Arkansas. That’s about 100 miles (160 kilometers) northwest of Pine Bluff, which is home to the Jefferson County Detention Center where Gullett and inmate Christopher Sanderson escaped earlier this week.

Spokeswoman Allison Bragg says Gullett was arrested by Dover police, but she did have not any details of what led to the capture.

Sanderson remains at large.

Escaped using 'dummy bodies'

Wesley Gullett and Christopher Sanderson were facing federal charges and being held in Jefferson County jail,located about an hour outside Little Rock, the U.S. Marshals Service said.

Marshals did not know when exactly the escape took place, but became aware around 4:30 a.m. Wednesday, authorities said.

Jefferson County Sheriff Lafayette Woods Jr. told the Pine Bluff Commercial the men escaped using "dummy bodies" in their beds to trick prison guards into thinking they were asleep.

Woods told the newspaper that the men got out using a "vulnerability" in the pod in which they were being held. The pair was able to climb to the roof and then over a fence to escape, Woods said.

Gullett, 30, is a leader of the brutal white supremacist gang New Aryan Empire, according to court records. In February, many members of the gang were indicted in connection with violent crimes tied to the group. Members were alsoaccused of gun and drug crimes.

Gullett was accused of attempted murder. Sanderson, 34, was being held on unrelated federal gun and drug charges.

Woods told the Pine Bluff Commercial that a lack of staffing and the need for renovations likely aided in their escape. The newspaper reported that other inmates tried to escape Tuesday but were stopped when drones saw them on the roof.

According to the New York Times, a $10,000 and $5,000 reward were being offered for information that leads to an arrest of Gullett and Sanderson, respectively.
