TOPEKA, Kan. (AP) — A court document reveals lurid details of sexual abuse allegedly committed against inmates by a former dental lab instructor at the Topeka Correctional Facility.

The suspect, 73-year-old Tomas Co, is facing seven chargesof unlawful sexual relations with seven different inmates at the women’s prison. The affidavit is based on interviews with 25 inmates during an investigation by a Kansas corrections department special agent. It says Co flaunted his authority over inmates, touched them inappropriately and removed the pockets of his pants to allow one inmate to touch him sexually.

A judge made the affidavit public Friday after The Topeka Capital-Journal asked for its release.

Co taught inmates to make dentures in a program designed to teach them a marketable skill. He was fired in December.

His attorney, Chris Joseph, said no one has independently verified the women’s stories.
