Activists occupied an animal facility at the University of Milan, Italy, at the weekend, releasing mice and rabbits and mixing up cage labels to confuse experimental protocols. Researchers at the university say that it will take years to recover their work.
Many of the animals at the facility are genetic models for psychiatric disorders such as autism and schizophrenia.
No arrests have been made following the 12-hour drama, which took place on Saturday, although the university says that it will press charges against the protesters. The activists took some of the animals and were told during negotiations that they would be permitted to come back later and take more. . .
