It was in the middle of this week that four sheep were killed.

Another six sheep were injured and had to be euthanized in connection with the attack.

It is a landowner who lives right next to, or on the border of, the Brängen district, which lies between Mullsjö and Ulricehamn.

A pair of wolves established themselves earlier this year in the area and have had puppies there.

The County Administrative Board will now take DNA to analyze which wolves may be behind the attack.
