Trial set on parents' rape of four teens COPENHAGEN, Denmark, Oct. 9 (UPI) -- A Danish man and woman are set to be tried on charges they sexually abused four young teenage girls, including their daughter. The court has set aside nine days to hear the case, which involves multiple charges of rape, assault and indecent exposure, The Copenhagen Post reported Monday. The 34-year-old mother is alleged to have tied up two of the girls, hanged them in the air by their legs and then watched as the 33-year-old father raped them. The man is charged with raping another girl multiple times after he threatened her with violence if she did not submit. Prosecutors allege the same victim was sexually abused by the mother as the father held the girl in a stranglehold. In another instance, officials charge the father made a video of a girl being sexually abused by the mother and a male acquaintance. All of the assaults are alleged to have happened in the couple's east Aalborg home in the northern region of Jutland.
