Washington, D.C. ? A fugitive animal rights activist believed to be hiding outside the United States has become the first domestic terror suspect named to the FBI’s list of “Most Wanted” terrorists.

Daniel Andreas San Diego, a 31-year-old computer specialist from Berkeley, Calif., is wanted for the 2003 bombings of two corporate offices in California.

Authorities say San Diego has unusual tattoos, including one that shows a burning field and proclaims, “It only takes a spark.”

FBI Assistant Director Michael Heimbach announced San Diego’s addition to its “Most Wanted” terrorists list at a press conference Tuesday.

Authorities believe he has fled the United States.

San Diego is the 24th person on the bureau’s wanted terrorist list, and the only domestic terror suspect.
