This means that Luxembourg has the first scientific proof of wolf presence since 1893.
The Nature and Forestry Agency could not exclude it being a wolf based on the bite marks.
It hoped that the bite marks contained enough saliva to send DNA tests to an institute in Germany to identify the type of animal.
The results of the laboratory analysis showed unequivocally that a wolf killed those sheep. It could be specified that the wolf comes from the Alpine region between Italy and France. Wolves from that population have already been located in the Vosges, Lorraine and Rhineland-Palatinate.
It is not known whether the wolf is still in Luxembourg or has moved on.
The farmer, whose sheep were killed, will receive compensation through the wolf action and management plan.
