It was a teenage boy on a quad bike who was on his way through the village who discovered the wolf pack. This was the magazine Jakt och jägare first to tell.
The 16-year-old tells P4 Gävleborg that he first met a lone wolf at the football field in Hällbo. After a short while came the rest of the herd which consisted of both adult animals and puppies.
Experts believe that the herd most likely came from the nearby Tönsberg district. The observation of wolves is not uncommon in Hällbo. Sheep were killed near the village by wolves this week.
