On Wednesday, students from River City High School were dismissed early following an unknown caller informing them that a shooting threat was coming to the West Sacramento campus.

According to the announcement posted by the Washington Unified School District on Facebook, the lockdown was called for the River City High campus on Raider Lane after the alleged threat was said to be “unsubstantiated”. The West Sacramento Police Department is looking into the claims, The Sacramento Bee reported.

At about 1:45 in the afternoon, the learners inside the campus were told to go home with the direction of law enforcement officials. The parking lot of a Target store nearby served as the temporary pick-up area of students who usually picked up at the campus, district officials said.

As usual, school buses serviced all of the students, and those who ride bikes and go to school by foot are told to head home directly, the school district assured.

Apart from the classes, activities after school and other extracurricular matters were called off.

An anonymous person has reached a school staff member, saying that shooting was coming toward the campus. The said staff urgently relayed the message to the West Sacramento police.

“The lockdown is a precautionary measure in accordance with our school safety plan,” part of the district officials’ statement on Facebook read. “This means that no one is allowed to enter or exit the campus until the WSPD has concluded its investigation and determined it is safe to do so.”

Parents were likewise told not to visit the campus on Wednesday afternoon. They were assured by the officials that updates will be announced.

“Though very troubling to hear, please take some slight comfort in knowing that all our students are safe and know that we handle any threat against our school safety with the utmost urgency,” district officials furthered in a social media post.
