Police on Monday arrested a fourth student this month for allegedly making a threat of violence against a Riverside school, and an additional student will be charged with conspiracy in connection with the same incident, authorities said.
A 13-year-old male was taken into custody and booked into a Riverside County juvenile detention facility on suspicion of criminal threats and conspiracy.
Late Monday night officers launched a “School Threat Assessment and Response,” or STAR investigation following reports from Central Middle School parents of an Instagram post depicting a “student with a possible firearm and a list of classmates’ names,” according to a Riverside Police Department statement Tuesday.
Police identified the student, and a search of his home uncovered a “realistic toy gun,” the statement said.
Earlier this month police arrested students, a 13-year-old and two 15-year-olds, enrolled in Chemawa Middle School, Arlington High School and Ramona High School.
