More on ALDF victory for chimpanzees

A spokeswoman for the Animal Legal Defense Fund said they were "thrilled."

"They're not going to be forced to perform unwillingly anymore," said Lisa Franzetta. "This is such a happy day to see these chimpanzees being retired."

The Animal Legal Defense Fund was set up by a group of primatologists, lawyers, scientists and actors who have started a campaign called No Reel Apes - to call for an end to the use of primates in entertainment.
