An animal rights group says it vandalized the home of a Los Angeles neuroscientist, adding yet another incident to a string of recent attacks on UCLA researchers. The incident is being investigated by the FBI and local authorities.

An anonymous statement posted on the Web site of the North American Animal Liberation Press Office described in detail how the perpetrators, members of the Animal Liberation Front, broke into the Beverly Hills house of Edythe London, a researcher at UCLA who has investigated how addiction influences behavior with experiments in monkeys. The interlopers smashed a window and flooded the home with a garden hose. UCLA officials told the Los Angeles Times that the flooding had caused between $20,000 and $40,000 of damage.

A written statement by UCLA chancellor Gene Block condemned the attack and the pattern of attacks in recent years. In June, a UCLA ophthalmologist, Arthur Rosenbaum, found an explosive underneath his car, but the device did not go off. Last summer, UCLA neuroscientist Dario Ringach said he was giving up his work with primates in response to pressure from animal rights groups. His announcement came shortly after the Animal Liberation Front took responsibility for an attempt to place a Molotov cocktail on the doorstep of another UCLA researcher, Lynn Fairbanks. (It was mistakenly placed on the doorstep of a neighbor, and also did not go off.)
