A Millikan High School student was arrested today after classmates reported overhearing him threaten to harm others at school, authorities said.

Officials said that at 11:15AM an Long Beach Police Department (LBPD) school resource officer assigned to the high school was advised by staff of a possible threat made by the student.

The student, identified only as a male juvenile, was then apprehended by police and remains in custody.

“Students remained safe the entire time, but the threat was overheard by classmates, who informed staff,” LBPD Sgt. Brad Johnson said.

The threat made at Millikan was not related to the unsubstantiated Poly High threat, authorities said.

“We thank the students who came forward with important information,” school officials said in a statement to the campus community. “Please know that we take all threats seriously, and we continue to work closely with our partners in law enforcement to keep our students safe.”

Anyone with information regarding a threat to a school is asked to call the Police Department immediately by dialing 9-1-1, or (562) 435-6711 for a non-emergency.
