LOS ANGELES (AP) — An animal rights group has sued the University of California, Los Angeles, for refusing to release records on its use of primates in lab experiments.

The lawsuit was filed Wednesday in Los Angeles on behalf of the group Stop Animal Exploitation Now.

Spokesman Michael Budkie says the group wants records about primates used in drug-testing and other research that have died since January 2012.

In a statement, UCLA says there’s a history of its researchers being subjected to violence by animal rights extremists.

The university says its policy about releasing information is legal and balances the public’s right to information with the need to protect scientists.
