The Sonoma County Office of Education (SCOE) said a threat posted on social media by a student’s father caused two schools to go into lockdown Monday morning. The Sonoma County Sheriff’s Office (SCCO) announced early Monday evening that the suspect was located and arrested by deputies in the 200 block of W.

The man was arrested with a concealed knife in his possession. A Cotati man who threatened online to bring a knife to his son’s school — prompting an evacuation Monday — was arrested hours later with a concealed blade in his possession, authorities said.
