Federal charges have been filed against a Utah trucker accused of keeping sex slaves in his semitrailer for months at a time.

Authorities have accused 54-year-old Timothy Jay Vafeades of kidnapping a 19-year-old female relative in May, taking her across the country and sexually abusing her hundreds of times.

Vafeades was arrested Nov. 26 in Clay County, Minn., by an officer who realized the teenager had a restraining order against Vafeades.

Authorities say an adult woman has since come forward saying Vafeades also held her against her will for three months after she met him at a Salt Lake City truck stop in 2012.

Vafeades was charged with kidnapping, transportation for illegal sexual activity, and possession of child pornography.

It wasn't immediately clear if Vafeades has an attorney.
