Police Investigate Online Threat Against California High School

September 6, 2018 Updated: September 6, 2018

Police are investigating an online threat of violence against California High School in San Ramon and plan to have an increased presence around the campus on Sept. 6, out of an “abundance of caution.”

Police are investigating the threat with the FBI and the San Ramon Unified School District, San Ramon police Capt. Denton Carlson said today. He would only say that the anonymous website post consisted of a “threat of violence.”

Carlson said police have no reason to believe at this time that the threat is credible but are not dismissing it. The IP address on the threat was traced to Europe, but authorities are not certain whether that is where the post originated because of the possibility of spoofing.
