No attorney for Thomas was listed in federal court records.
Thomas was arrested Saturday night after allegedly asking someone online to arrange a marriage between him and the person’s daughter.
An undercover officer said Thomas told him he wanted to keep the girl at home for sex.
Dettelbach said moving the case to federal court reflected a priority of his office. “The conduct laid out in these charges is disturbing,” he said in a statement.
“Our office remains committed to working with the FBI and all our law enforcement partners to defend our children and fight human trafficking.”
Dettelbach, whose office prosecutes federal crimes in 40 counties in northern Ohio, has won convictions against 32 people for human trafficking and related crimes since 2010.
Thomas had been charged in state court with human trafficking, attempting to commit kidnapping and to commit rape and possession of criminal tools. His bond was $2 million on the state charges.
A police search of Thomas’ home near Akron turned up sexual paraphernalia, videos, several handguns and rifles and a rifle with a mounted grenade launcher, according to The (Canton) Repository. A computer and electronic storage devices also were seized.
