An Athens court yesterday imposed heavy jail terms, ranging from 18 to 56 years, on four people found guilty of brutal sexual exploitation of minors. The four included a woman from Ilion, western Athens, who forced her three underage children to work as sex slaves two years ago. The mother of three was sentenced to 37 years in jail for making her daughter, then aged 11, and her two sons, then aged 8 and 9, have sex with clients. The latter included a 63-year-old priest and an 83-year-old pensioner, who were sentenced to 24-year and 56-year terms respectively. The court also sentenced the mother’s boyfriend to 18 years in jail after finding that he helped her force the children into sex and to photograph and video some of the encounters. In one case, the court heard, the mother held the arms of her daughter while the child cried and tried to resist the sexual abuse.
