It was a university guard who recently sounded the alarm. Handwriting was compared and experts came to the conclusion that the woman student's alleged copy was in fact written by a former student, her partner.
How long exactly the fraud has been going on for is unclear. KU Leuven's Antoon Boon told VRT News: "We went back in time as far as we could. Exam copy is destroyed when it can no longer be contested. We have established that the fraud took place this year and last."
KU Leuven hasn't divulged what the student was studying but the fraud occurred at a campus outside the city of Leuven.
Antoon Boon: "Because of the large numbers in Leuven there are strict ID checks. At smaller centres outside Leuven this is not the case. We have now requested stricter checks there too."
The female student is now banned from registering at the university for several years.
