Twenty sheep belonging to hobby farmer Richard Muskens from Helvoirt died in two suspected wolf attacks in the Vughtse Gement nature reserve between Vught and Den Bosch. Muskens found dead and injured sheep on Thursday, and five more died the following night; a veterinarian euthanized some surviving animals because of their injuries.

A veterinarian said the bite wounds were consistent with a wolf attack, but DNA tests still have to confirm this. Muskens removed about 100 remaining sheep from the reserve as a precaution and said they are stressed; some pregnant ewes may be affected.
