Overnight on January 8th, news broke on the "Portland Meat Collective" website that somewhere between 18 and 23 rabbits had disappeared from the backyard of one of their "instructors" the day before they were to be killed as part of a "how to" self-butchery class. Nearly a week passed without any further news or claim of responsibility.

Then, in a tragic development Friday, January 13th, news came that the rabbits had been located and returned to the school to be killed.
...
While there has been no claim of responsibility made by the ALF or anyone else, there is a precedent for the Animal Liberation Front locating and re-liberating animals that have been returned to their abusers after rescues.
