You remember her as Chloe on the hit TV show "Smallville" from the early 2000's; Allison Mack has been a bit busy since the shows finale in 2011. Mack was arrested in New York for her alleged involvement in the "self-help group" NXIVM, which has been accused of branding female followers and using blackmail to coerce them into sex.
Mack was charged with "sex trafficking, sex trafficking conspiracy and forced labor conspiracy." The founder of NXIVM, Keith Raniere was arrested on similar charges in March.
