SHEBOYGAN, Wis. (AP) -

The Sheboygan County Sheriff's Office says the recent thefts of more than 300 baby mink from a Wisconsin farm doesn't look like the work of animal rights activists.

Dittrich Mink Ranch in Mosel reported the mink stolen on May 13.

Sheriff's Capt. Dave Adams tells Sheboygan Press Media the thefts don't fit the profile of an animal rights group because the mink weren't taken all at once and no adult mink were stolen. He says activists usually release as many animals as possible and often focus on adult animals.

Sheboygan County is one of the largest mink-producing areas in the country, and farms there have been the targets of multiple raids by animal rights groups over the years.
