A New Jersey man accused of moving into his daughters college dormitory and abusing her roommates is facing federal charges, including sex trafficking, extortion and forced labor.

Lawrence Ray, 60, appeared before a Manhattan judge on Tuesday after being accused of exploiting and abusing at least five Sarah Lawrence College students on and off campus over eight years.

For the better part of the last decade, we allege there was no limit to the abuse Rays victims received, and there is no way of knowing the amount of damage he may have caused them in the years to come, FBI Assistant Director William F. Sweeney Jr. said in a statement .

Rays arrest followed a stunning expose by New York magazine last April about the alleged psychological and sexual abuse, which led to the federal investigation.

At the time the expose was published, Sarah Lawrence denied knowing that Ray was living on campus. A representative for the school did not immediately respond to HuffPosts request for comment on Wednesday.
