Officers are investigating a threat of violence phoned into our Department just now directed at Palo Alto High School. Out of an abundance of caution, expect a heavy police presence in the area while we investigate. The school is on lockdown as a precaution. pic.twitter.com/uVYwVL0uxe— Palo Alto Police (@PaloAltoPolice) March 29, 2018
