A French Catholic school plans to DNA test more than 500 male faculty members and students to find out who raped a 16-year-old, who was sexually assaulted in a school bathroom last year.
Police say anyone who refuses the DNA test will be considered a suspect.
The private school in La Rochelle, Fénelon Notre-Dame, will test 527 males starting Monday, The Guardian reported. That includes, 475 students, 31 staff and 21 other employees.
Saliva swabs will be collected by 18 police officers who will be at the school Monday, Tuesday, and Wednesday.
The female victim was raped on Sept. 30 and DNA samples taken from her clothing did not match family or friends. She was assaulted in the dark after an automatic light timer shut the lights off, and she is unable to identify her attacker.
"We have followed every lead before going down this route. We don't have any other choice,” head teacher, Chantal Devaux, told parents Friday.
The French Human Right League called the school’s methods "disproportionate, threatening and traumatizing."
"I understand the argument that those who have done nothing wrong have no reason to refuse. But why should refusal be considered an admission of guilt?" asked Pierre Tartakowsky, president of the French Human Rights League.
"The issue is to know whether the sole fact of being a pupil at this establishment is a plausible enough reason to become a suspect," said Françoise Martres, the head of the French magistrates' union.
Investigators say any DNA sample taken that does not match the assailant's will be destroyed.
