Authorities say workers at a fur farm in western Wisconsin are trying to recapture thousands of mink that were released last week, apparently during a raid by animal activists. The Trempealeau County Sheriff’s Office says a hole was cut in a chain-link fence at Olsen Fur Farm late Friday or early Saturday, allowing about 3,000 mink to escape. Detective Erica Koxlien said Thursday that farm workers have been using traps and fishing nets to recapture the mink. The Milwaukee Journal Sentinel reports the Animal Liberation Front, which is labeled an extremist group by the FBI, shared an anonymous post claiming responsibility for releasing the mink.
