Los Angeles (AP) - An official says a primate researcher at the University of California, Los Angeles, has received a package containing razor blades and threatening messages.
UCLA spokesman Phil Hampton said Tuesday the package was sent earlier this month to David Jentsch, a psychologist and neuroscientist who does research on rodents and primates.
The Animal Liberation Front on Tuesday released a statement saying it had sent razor blades covered in AIDS-infected blood to Jentsch and one of his researchers.
It was not known if the blades Jentsch received were contaminated. No one was injured and the other researcher had not received any packages.
UCLA researchers have been the target of several recent attacks. Last year, Jentsch's car was set ablaze.
