Authorities say a Northern California man has been arrested on suspicion of making death threats against Sen. Barbara Boxer.
San Rafael police spokeswoman Margo Rohrbacher says Kevin Joseph O'Connell was arrested Saturday and is jailed on $500,000 bail.
Rohrbacher says the 47-year-old O'Connell was arrested near his home in San Rafael and is scheduled for arraignment Tuesday. It was not clear if he had hired an attorney.
Police say they received reports this week that the threatening messages were left on voicemail at Boxer's office, and they identified the caller as O'Connell. Rohrbacher says police worked with the FBI on the case, but made the arrest themselves and are pursuing state charges.
She says policy prevents her from saying whether O'Connell has a police record or previous contact with authorities.
