A Livermore man who was convicted of threatening to release anthrax into the Oakland federal building in 1999 has been indicted by a federal grand jury on charges that he made another threat, court records show.

Charles Redden, 41, mailed a threat to an undisclosed party June 16 and did so again Jan. 4, said the indictment handed down Thursday by a federal grand jury in San Francisco. No further details were released in the indictment, which accuses Redden of two counts of mailing threatening communications.

Redden was convicted of making a biological-weapons threat and sentenced in 2002 to five years in federal prison. Prosecutors said he telephoned the Oakland court clerk's office from the Alameda County Jail in January 1999 and warned that he planned to spread anthrax into the federal building's air-conditioning system.
