Detectives carrying out mass DNA testing at a French lycée to trace a rapist say only one student has refused to give a sample, reports The Guardian.
The young man, who is over 18, told police he had personal reasons for not giving a sample as part of the police operation at the private Catholic lycée Fénélon-Notre-Dame at La Rochelle.
On Wednesday morning, officers were testing the last of the 475 pupils, 31 teaching staff and 21 other male adults at the secondary school. It is the first time such an operation has been carried out in a French educational establishment.
A handful of tests are expected to take place on Thursday on those minors and adults who were unable to attend before, after which all samples will be sent to two French laboratories for analysis.
Many of those tested were minors and the judge leading the inquiry had required the written authorisation of their parents.
