The leader of an embattled upstate New York self-help organization has been hit with child pornography charges.

Federal prosecutors announced the new charges against Keith Raniere on Wednesday.

Raniere was arrested last year in a sex-trafficking investigation of his Albany-based NXIVM group. Prosecutors say a secret society within the organization branded women with his initials and forced them to have sex with him.

Earlier Wednesday, group co-founder Nancy Salzman pleaded guilty to conspiracy during a hearing in federal court in Brooklyn on Wednesday.

Raniere is set to go on trial next month. Also charged in the case are Salzman’s daughter as well as Seagram liquor fortune heiress Clare Bronfman and TV actress Allison Mack.

There was no immediate response from Raniere’s lawyer on Wednesday.
