Allison Mack has been arrested for her alleged involvement in a sex cult.

On Friday, both the Smallville actress and Keith Raniere were charged with sex trafficking, sex trafficking conspiracy, and forced labor conspiracy, the U.S. Attorney’s Office for the Eastern District of New York confirmed to Yahoo Entertainment. Raniere, the founder of the self-help group NXIVM and the alleged cult leader, was arrested last month.

Within NXIVM, there was reportedly a secret “sorority” called DOS, also known as “Lord/Master of the Obedient Female Companions.” Mack, 35, was allegedly a DOS Master who recruited and directed slaves to have sex with Raniere, also known as “Vanguard.”

“As alleged in the indictment, Allison Mack recruited women to join what was purported to be a female mentorship group that was, in fact, created and led by Keith Raniere,” U.S. Attorney Richard P. Donoghue said in a statement. “The victims were then exploited, both sexually and for their labor, to the defendants’ benefit. This Office and our law enforcement partners are committed to prosecuting predators who victimize others through sex trafficking and forced labor.”

Yahoo reached out to a representative for Mack, who had no comment. During Friday’s arraignment in New York, one of her defense lawyers entered a plea of not guilty on her behalf and she was ordered detained by the judge.

The actress — who played Chloe Sullivan on the CW show from 2001 to 2011 — has frequently mentioned Raniere on her website and on social media.

Mack’s former Smallville co-star Kristin Kreuk was once a member of NXIVM.

However, Kreuk released a statement saying she had no idea about DOS.

Mack has a bail hearing set for Monday. Raniere will be arraigned at a later date. The FBI is asking “anyone who might have been a victim” to reach out so it can continue to unravel this “pyramid scheme.”
