A London court has ruled that U.S. citizen Daniel San Diego, accused of carrying out bombings linked to animal testing in California in 2003, can be extradited from Britain to face trial in the United States.

San Diego, 47, was found in Wales in November 2024 and had been on the FBI’s most-wanted terrorist list since 2009, making him the first domestic terrorist listed alongside figures such as the late al Qaeda leader Osama bin Laden.

He is alleged to have carried out two bombings claimed by the so-called Revolutionary Cells of the Animal Liberation Brigade. No one was injured in either incident. The first targeted biotechnology firm Chiron Inc. near Oakland in August 2003, with authorities discovering a second bomb possibly intended for first responders. A month later, a nail bomb detonated outside nutritional products company Shaklee, also claimed by the group.

San Diego’s lawyers had argued that extradition would deny him a fair trial, citing concerns over political influence and the U.S. Department of Justice under President Donald Trump. However, Judge Samuel Goozee dismissed these claims, stating there was “no evidence of any improper political involvement in [San Diego’s] case or any evidence of any presidential interference… now or in the future.”

U.S. authorities have highlighted that both Chiron Inc. and Shaklee had links to Huntingdon Life Sciences, a British company long targeted by both legal and illegal protests over animal testing.
