NXIVM founder Keith Raniere is scheduled to appear in federal court this week.

The leader of a so-called cult based in the Capital Region is set to be arraigned in Brooklyn on charges of sex trafficking and conspiracy to commit forced labor. That's according to the U.S. Attorney for the Eastern District of New York.

This week, Attorney General Eric Schneiderman's office confirmed its investigation into a non-profit called the Ethical Science Foundation, connected to NXIVM, is on hold while the federal investigation intensifies.

Raniere, also identified as "The Vanguard" in court documents, was arrested in Mexico last month.
