REDLANDS >> Redlands police have increased officer presence at Redlands High School after a student was arrested Monday on suspicion of making threats.

Redlands police arrested a 14-year-old boy for allegedly making criminal threats, according to Carl Baker, city spokesman. The student is in custody at Juvenile Hall, he said.

Police have no reason to believe that there is any further threat to the school or students, Baker said in an email.

The unidentified student was taken into custody after police launched an investigation Monday prompted by several calls from concerned parents.

The case has been forwarded to the juvenile district attorney for review, Baker said.

According to one parent’s text message, the student was threatening to “shoot up RHS” Tuesday morning. It went on to ask other parents to call police and spread the word about the reported plot.

According to police, the threats were made on social media and targeted staff and students at the school.

The motive was not released.

Jon Best, director of student services at the Redlands Unified School District, said the threats were reported to on-campus security who then alerted the police. The district auto-dialed students’ homes to inform parents about the threats.

Students were told by their teachers Tuesday morning, Best said.

Best said this was an isolated incident involving one student and said the district does not see any future threats to students or staff.

The district is conducting an investigation and will determine any disciplinary action to be taken, he said.

“We take these types of things very seriously,” Best said. “It’s crucial that our security folks have great relationships with kids, and it’s evidenced by the fact that they felt comfortable coming to the security officer working on campus after school to inform him of the situation.”

The incident is still under investigation.
