The 36-year-old Wisconsin man was arrested on allegations that also include theft, unlawful phone use and harassment with a death threat in a domestic abuse investigation, Fond du Lac Police Captain Steve Klein said on Wednesday.
"It is a case that keeps getting stranger," Mr Klein said. "More information will come out in the [charging] complaint."
No charges were filed on Wednesday. Fond du Lac County Assistant District Attorney Devra Ayala did not return a telephone message seeking comment.
Four women, including the man's wife and two women alleged to
have been his lovers, are accused of luring him to a hotel room
in Stockbridge last Thursday before tying him up, blindfolding
him and gluing his penis to his stomach.
Each is charged with being party to false imprisonment, a felony, and one is charged with fourth-degree sexual assault, a misdemeanour.
The women are free on $US200 ($240) bail. Therese Ziemann, Wendy Sewell and Michelle Belliveau are scheduled to make a court appearance in Calumet County on Monday. The man's wife returns to court on August 17.
Mr Klein said the man was arrested on Tuesday in Chilton, where he had been staying in a motel, after a complaint was filed with the Fond du Lac Police Department.
The child abuse allegation involves one of his children, Mr Klein said. He would not say whether one of the women involved in the Stockbridge incident made the complaint that led to his arrest.
The man declined a request to be interviewed, said Sheriff's Sergeant Amy Schoepke at the Fond du Lac County Jail.
