In 1985, a raid took place at a laboratory belonging to the University of California, Riverside (UCR) that resulted in the removal of a monkey by the Animal Liberation Front (ALF).

[4] The raid also saw the release of 467 mice, cats, opossums, pigeons, rabbits, and rats, and a reported $700,000-worth of damage to equipment.

[5] A spokesman for the university said that allegations of animal mistreatment were absolutely false, and that the raid caused long-term damage to its research projects.

[9] Newkirk writes that the ALF was alerted to the laboratory's work by a student who had reported the Britches' situation to Last Chance for Animals.

[10] On April 21, 1985, ALF activists, including Sally S, a businesswoman in her mid-30s,[11] broke into the laboratory and removed Britches along with around 467 other animals, taking footage of the raid, which they handed anonymously to PETA.

[12] Activists say they found Britches, who was given his name by the researchers, alone in a cage with bandages around his eyes and a sonar device attached to his head.

He was clinging to a device covered in towelling that had two fake nipples attached, apparently intended to serve as a surrogate mother.

Theodore Hullar, UCR's executive vice chancellor, said the researchers' work had been set back years.

There is an open space between upper and lower lids of both eyes of about one quarter inch, and sutures are contacting corneal tissue resulting in excessive tearing ...

"[4]PETA released a film called Britches that included footage from the raid and the ALF's treatment of the monkey afterwards.

[15] A UCR spokesman said allegations of animal mistreatment were "absolutely false", and that there would be long-term damage to some of the research projects.
