Long Beach police took a sophomore at Millikan High School into custody earlier this week after the student made threats about violence happening at the campus, according to authorities.

Police said they first got reports about the threats on Thursday around 8:30 a.m.

Officers went to the campus and later took the 15-year-old into custody, Long Beach Police Department spokeswoman Arantxa Chavarria said.

“The suspect was not in possession of any weapons or ammunition at the time of arrest and is being held at Los Padrinos Juvenile Hall,” Chavarria said.

Police would not give details about the threats, saying only that they were “related to violence in school.”

The student’s parents are cooperating with investigators, according to authorities.

“There is no further threat to student safety based on this investigation,” Chavarria.

In a statement on the Millikan High website, school officials said students told them about the threats.

“We again thank and commend the students who shared their concerns with us, and we encourage all students to speak up without hesitation about any potential safety issue. The safety of our students is always our top priority,” it said.

Long Beach Unified School District spokesman Chris Eftychiou said school officials notified parents about the situation on Thursday.

Police are still investigating and asked that anyone with information about the situation to call Detective Carlos Grimaldo at 562-570-1425.

“The Police Department strongly promotes the ‘See Something, Say Something’ approach to public safety,” Chavarria said. “Parents, students and community members should immediately report any activity or information that poses a potential threat to themselves or others.”

Editor’s note: Police initially said the threats were reported on Wednesday; the story has been updated to reflect that the threats were reported Thursday.
