(The Hill) -- Daniel Andreas San Diego, a fugitive on the FBI’s “Most Wanted Terrorist” list, was captured in the United Kingdom on Monday after more than 20 years. San Diego, 46, wanted for his alleged involvement in two bombings in Northern California in the 2000s, was arrested in Wales, the U.K.’s National Crime Agency (NCA) said. The California native was detained by NCA officers in an operation that involved the North Wales Police and the Counter Terrorism Police.  San Diego now faces extradition to the United States to face charges, according to the NCA.  A photo of Daniel Andreas San Diego, top right, appears on a poster of the FBI's most wanted terrorists during a news conference announcing his addition to the most wanted terrorist list, Tuesday, April 21, 2009, at FBI Headquarters in Washington. FBI Director Christopher Wray lauded San Diego’s arrest on Tuesday.  “Daniel San Diego’s arrest after more than 20 years as a fugitive for two bombings in the San Francisco area shows that no matter how long it takes, the FBI will find you and hold you accountable,” Wray said in a statement. “There’s a right way and a wrong way to express your views in our country, and turning to violence and destruction of property is not the right way.” San Francisco watchdog Ricci Wynne arrested, suspected of pimping San Diego, who was put on the FBI’s “Most Wanted Terrorist” list in 2009, was sought out by authorities over his alleged involvement in two bombings in the San Francisco area, according to the FBI.  In August 2003, two bombs detonated on the campus of Emeryville biotechnology firm Chiron Corp. just around one hour apart. No one was injured in those explosions.  The fugitive was also allegedly involved in a “bomb strapped with nails” that exploded at a nutritional products corporation, Shaklee Corp., in Pleasanton, Calif., according to the FBI. No one was injured in the incident.  San Diego was indicted in the U.S. District Court in July 2004. The FBI said he has ties to animal rights extremist groups and that he has worked as a computer network specialist in the past.
