Federal and local officials on Tuesday announced a $110,000 reward for information leading to arrests and convictions in the attempted firebombing of a prominent UCLA eye doctor's car last month.
A group known as the Animal Liberation Brigade claimed responsibility on a website for the act, which authorities described as "domestic terrorism."
On June 24, an incendiary device was lighted next to a car parked at the Westside home of Dr. Arthur Rosenbaum, who is chief of pediatric ophthalmology at UCLA's Jules Stein Eye Institute.
The device did not ignite, but authorities said it had the potential to cause great harm.
Rosenbaum has conducted research that, among other things, used monkeys to test procedures correcting severe cross-eyed conditions.
UCLA says that all animal research at the university is humane and meets federal standards.
At a news conference Tuesday at FBI offices in Westwood, law enforcement officials urged anyone with information about last month's incident to call the FBI at (310) 477-6565; the federal Bureau of Alcohol, Tobacco, Firearms and Explosives at (888) 283-2662; or local law enforcement agencies.
