No one was in the building at the time but the courthouse was shut for the day. A spokesperson for Cal Fire says the impact of the explosion shattered the building's doors. Deputies say those responsible will face serious charges. Undersheriff Frank Benard said, "Arson of course is a serious felony crime. Making a bomb threat would be considered a terrorist threat as well because this went way beyond someone making a threat to the facility."
Detectives say there are surveillance cameras inside and outside the courthouse. Investigators will sift through that footage in the coming days.
Courthouse administrators tell Action News the court is expected to reopen tomorrow.
