Controversial self-help group Nxivm has suspended operations following the high-profile arrests of Smallville actress Allison Mack and group co-founder Keith Raniere on sex trafficking and forced labor charges.
According to a message posted on Nxivm’s website, “we are suspending all Nxivm/ESP enrollment, curriculum and events until further notice.”
The message was posted sometime after Mack’s April arrest, but it was not clear exactly when.
The message continues: “While we are disappointed by the interruption of our operations, we believe it is warranted by the extraordinary circumstances facing the company at this time. We continue to believe in the value and importance of our work and look forward to resuming our efforts when these allegations are resolved.”
Nxivm, which has not responded to numerous requests for comment from PEOPLE on the allegations against Mack and Rainere, has been described by at least one former member as a “cult.”
Mack was charged with sex trafficking, sex trafficking conspiracy and forced labor conspiracy. The actress, best known for her years-long role as Chloe Sullivan on The WB’s Smallville, is facing a minimum sentence of 15 years in prison if convicted on all of her charges.
Raniere faces the same charges and potential prison sentence. Both he and Mack have pleaded not guilty.
Federal investigators have accused Mack of recruiting women into a sub-group of NXIVM purported to be a female mentorship group to address their weaknesses but was actually a group created by Raniere that allegedly took advantage of women sexually.
“The victims were then exploited, both sexually and for their labor, to the defendants’ benefit,” Richard P. Donoghue, U.S. Attorney for the Eastern District of New York, alleged in a statement issued at the time of Mack’s arrest.
Nxivm is based out of Albany, New York, and has been the subject of scrutiny from both law enforcement and journalists as it came under fire from Dynasty actress Catherine Oxenberg, whose estranged daughter, India, joined the group in 2011.
Oxenberg first opened up to PEOPLE last year about how she believed India had been “brainwashed” by Nxivm.

In the fall, India posted on Facebook that she was “absolutely fine, great actually [and] I would never put myself or the people I love into any danger.”
For the past two decades, an estimated 16,000 people have paid as much as $3,400 for an executive coaching workshop offered by Nxivm, which promises to take participants on a journey of personal discovery and development, according to previous PEOPLE reports.
The criminal complaint against Raniere — known as “Vanguard” to his followers — alleged that he encouraged the formation of a secretive subgroup within Nxivm called “Dominus Obsequious Sororium,” (DOS) in which women were coerced into serving as sex slaves to their male masters.
The complaint, which was previously obtained by PEOPLE, outlines how authorities believe the women were forced to turn over “collateral” — or potentially-damaging personal information or materials, such as nude photographs, with which they later could be blackmailed.
The women allegedly victimized by Mack allegedly believed their “collateral” would be released if they did not engage in sexual activity with Raniere, the statement on Mack’s arrest alleges.

The complaint against Raniere additionally alleges the women were branded with Raniere’s initials, as he “alone forms the top of the pyramid as the highest master.”
A cauterizing pen was used to make the permanent marks near each person’s pubic region, the complaint alleges.
In statements previously posted to Nxivm’s website, Raniere said all involved in DOS were consenting adults and that Nxivm was not involved in what he called a “sorority.”
In the fall, the group denounced a New York Times article about them as “a criminal product of criminal minds.”
Mack and Raniere are scheduled to stand trial on Oct. 1.
