There were three instances of people sending threats to local high schools or high school students Monday and officers later made three arrests.
River City High School in West Sacramento was locked down Monday while police investigated an alleged threat left anonymously in the school’s main office.
Police said officers are on campus, and students were gradually being released.
A male River City student was later arrested on suspicion of making criminal threats, according to the West Sacramento Police Department.
Vista Del Lago High School was on precautionary, temporary lockdown Monday after a threat was sent through a text message by 18-year-old student Ryan Bernal. Bernal was not at the school Monday.
The Folsom Police Department reports Bernal had not planned on carrying out his threat. He was, however, arrested on suspicion of making criminal threats.
In Roseville, a 19-year-old was arrested after sending threats to an Adelante High School student over social media. Oakmont High School administrators were also tipped off about the threats and contacted police.
Roseville officers arrested the man in a restaurant parking lot on Douglas and Sierra College boulevards. They found an AR-15 rifle in his car.
Adelante students had already been let out of school for the day at the time of the arrest.
Lodi Police were on high alert for a moment Monday as well when a rumor about a shooting went around Tokay High School. An alleged anonymous phone call was never made to the school and the threat was not found to be credible.
